The Basis of Islam
In the name of Allāh, the Most Gracious, the Most Merciful;
All the praise and Thanks is due to Allāh, the Lord of al-'ālamīn. There is none worthy of worship except Allāh, and that Muhammad, Sallallāhu ‘alayhi wasallam is His Messenger.
The basis of Islam is built on two foundations, the belief in the ‘Six Articles of Faith’ and adheres to the ‘Five Pillars of Islam’.
The Five Pillars of Islam consist of the following:
1. Declaration of Faith or Shahadah.
2. Ritual Prayer or Solah.
3. Obligatory Charity or Zakah.
4. Fasting or Sawm (siyam).
5. Pilgrimage or Hajj
This article provides an introduction to the first pillar of Islam: the Muslim Declaration of Faith, or the Shahadah which is the basis of the foundation of Islam.
The Declaration of Faith.
In Arabic testimony of faith, means Shahadah. It is the basis of the religion of Islam. The shahadah is to testify to two things:
Firstly: None is rightfully worshipped except God [Lā-ilāha -ill-Allāh], and
Secondly: Muhammad is the Messenger of God [Muhammad-ur-Rasūl-ullah].
It is through the belief and attestation of these two phrases one enters the fold of Islam. It is the motto of the believers which they maintain throughout life, and the basis for all their beliefs, worship and existence.
1. The Statement ‘Lā-Ilāha-ill-Allāh’. 
This testimony is the most important aspect of the religion of Islam, as it asserts the belief in Tawhid, or the Oneness and uniqueness of God, upon which the whole religion is built. For this reason, it is called, “The declaration of Tawhid”. This uniqueness and oneness necessitates God’s sole right to worship and obedience. The religion of Islam is basically a way of life in which a person worships and obeys the orders of God and none else. The first part of this testimony states that God has the exclusive right to be worshipped inwardly and outwardly, by one’s heart and limbs. It is the only true monotheistic religion, stressing that no worship should be directed to any other except God. For this reason, we see that in many narrations, the Prophet SAW, said that whoever says this phrase and practices it will enter Paradise for eternity, and whoever opposes it will doomed to Hellfire for eternity.
This declaration also reiterates the purpose of one’s life, which is the worship of God alone, and obviously, the purpose of one’s existence and being is the most important aspect in one’s life. God says in the Quran:
“And I have created neither jinn nor humans, except to worship Me Alone.” [Surah Ad-Dhariyat, 51:56]
The message of Tawhid found in this declaration is not particular to Islam. It was the message brought by all prophets. Since the dawn of humanity, God sent messengers to every people and nation, commanding them to worship Him Alone, and to reject all false deities. God says:
“And indeed We have raised amongst every nation a messenger, [commanding them] ‘Worship God, and reject all false deities….” [Surah An-Nahl, 16:36]
In the Islamic doctrine, not only can no one be worshipped apart from Him, absolutely no one else can be worshipped along with Him. He has no partners or associates in worship. Worship, in its comprehensive sense and all its aspects, is for Him alone. God’s right to be worshipped is the essential meaning of Islam’s testimony of faith: Lā ‘ilāha ‘illā llāh. A person becomes Muslim by testifying to the divine right to worship. It is the crux of Islamic belief in God, even all of Islam. It is considered the central message of all prophets and messengers sent by God - the message of Abraham, Isaac, Ishmael, Moses, the Hebrew prophets, Jesus, and Muhammad, may God exalt their mention. For instance, Moses declared:
“Hear, O Israel The Lord our God is one Lord.” [Deuteronomy 6:4]
Jesus repeated the same message 1500 years later when he said:
“The first of all the commandments is, “Hear, O Israel; the Lord our God is one Lord.” [Mark 12:29]
…and reminded Satan:
“Away from me, Satan! For it is written: Worship the Lord your God, and serve Him only.” [Matthew 4:10]
Finally, the call of Muhammad, some 600 years after Jesus, reverberated across the hills of Makkah, ‘And your God is One God: there is no god but He.’ [Surah Al-Baqarah, 2:163]. They all declared clearly:
“Worship God! You have no other god but Him.” [Surah Al-Araf, 7:59, 60, 73, 85; Surah Hud, 11: 50, 61, 84; 23, 32]
It is only when this notion of Tawhid is ingrained in the heart and minds of a person that they will willingly follow the commandments of God and renders all worship to Him Alone. For this reason, the Prophet SAW, called his people for thirteen years in Makkah to Tawhid alone, and only a minimal amount of worship was mandated at that time. It was only when this notion became firm in the believers’ hearts and they were willing to sacrifice even their own lives for it that the majority of the other commandments of Islam were revealed. If this base is missing, nothing after it will be of avail.
Many people ignorant of Islam have misconceived notions about the Allāh, used by Muslims to denote God. Allāh is the proper name for God in Arabic, just as "Elah", or often "Elohim", is the proper name for God in Aramaic mentioned in the Old Testament. Allāh is also His personal name in Islam, as "YHWH" is His personal name in Judaism. However, rather than the specific Hebrew denotation of "YHWH" as "He Who Is", in Arabic Allāh denotes the aspect of being “The One True Deity worthy of all worship”. Arabic speaking Jews and Christians also refer to the Supreme Being as Allāh. 
1.1. The Meaning of Lā-Ilāha-Ill-Allāh 
La ilaha ill Allāh literally means “There is no god [deity] except Allāh” which is Nothing deserves worship except God [Allāh].Here; god with a small case ‘g’ is anything which is worshipped. What this declaration implies is that although there might be other gods and deities being worshipped by humans in existence, none of them are rightfully worshipped, meaning that no object considered as a god has any right to that worship, nor does it deserve it, except the One True God. Thus, la ilaha ill Allāh means, “There is no god rightfully worshipped except Allāh.”
1.2 Meaning of Lā-Ilāha… (There is no god rightfully worshipped…)
These two words deny the right of any created being to worship. Muslims reject the worship of everything besides God. This rejection extends to all superstitions, ideologies, ways of life, or any authority figures who claim divine devotion, love, or absolute obedience. God in the Quran mentions in many places that all things which people take as objects of worship besides Himself do not deserve any worship, nor do they have any right to it, as they themselves are creations and have no power to bring any benefit.
“Yet they have taken besides Him other gods that created nothing but are themselves created, and possess neither [the power to] harm nor benefit for themselves, and possess no power [of causing] death, nor [of giving] life, nor of raising the dead.” [Surah Al-Furqan, 25:3]
One usually worships another object or being because they believe that it has some special power, such as some control over the universe, some power to benefit or harm, or that it deserves worship in and of itself due to its greatness of being. God negates the notion that these things which people take as objects of worship, whether they be aspects of nature, such as the wind, trees, stones, rain; or conscious beings, such as humans, prophets, saints, angels, kings, have any power in themselves. They are mere creations like the worshippers themselves and have no power to help even their own selves, and thus they are not to be worshipped. They are mere creations with deficiencies, subject to the Will of God, and thus they do not deserve any aspect of worship.
In reality, many believe in the ultimate control and power of God, but they imagine the Divine Kingdom of God to be like earthly kingdoms. Just as a king has many ministers and trusted associates, they imagine ‘saints’ and minor deities to be our intercessors to God. They take them as agents through whom God is approached, by directing some acts of worship and service to them. God says:
“And verily, if you ask them: ‘Who created the heavens and the earth?’
Surely, they will say: ‘God.’
Say: ‘Tell me then, the things that you invoke besides God, if God intended some harm for me, could they remove His harm, or if He intended some mercy for me, could they withhold His Mercy?’
Say: ‘Sufficient for me is God; in Him those who trust [i.e. believers] must put their trust.’” [Surah Az-Zumur, 39:38]
In truth, there are no intercessors in Islam. No righteous person is to be venerated, nor is any other being to be worshipped. A Muslim directs all worship directly and exclusively to God.
1.3. Meaning of …Ill-Allāh (…Except Allāh)
After denying the right of any created being to be worshipped, the shahadah affirms divinity for God alone, with ‘…except God’. In many places in the Quran, after God negates that anything of the creation has power to bring benefit and harm, thus deserving no worship, He states that He Himself is to be worshipped, as He has control over and ownership of the whole universe. It is God Alone who provides for his creation; He is in total control. He is the only one who can bring benefit and harm, and nothing can impede His Will from becoming reality. Thus it is He Himself, through His perfection, through His ultimate powers, due to his total ownership, and due to His greatness, which deserves all worship, service and veneration exclusively.
“Say: ‘Who is the Lord of the heavens and the earth?’
Say: ‘[It is] God.’
Say: ‘Have you then taken (for worship) deities other than Him, such as have no power either for benefit or for harm to themselves?’
Say: ‘Is the blind equal to the one who sees? Or darkness equal to light? Or do they assign to God partners who created the like of His creation, so that the creation [which they made and His creation] seemed alike to them?’
Say: ‘God is the Creator of all things; He is the One, the Irresistible.’” [Surah Ar-Rad, 13:16]
God also says:
“You worship besides God only idols, and you only invent falsehood. Verily, those whom you worship besides God have no power to give you provision. So seek your provision from God [Alone], and worship Him [Alone], and be grateful to Him. To Him [Alone] you will be brought back.” [Surah Al-‘Ankabut, 29:17]
And God says:
“Is not He Who created the heavens and the earth and sends down for you water [rain] from the sky, whereby We cause to grow wonderful gardens full of beauty and delight? It is not in your ability to cause the growth of their trees. Is there any ilah [god] along with Allāh? Nay, but they are a people who ascribe equals [to Him]!” [Surah An-Naml, 27:60]
As God is the only being who is deserving of worship, anything worshipped besides or along with Him is done so wrongfully. All acts of devotion are to be directed towards God alone. All requirements should be sought through Him. All fear of the unknown should be feared from Him, and all hope should be placed in Him. All divine love should be felt for him, and all that one hates should be hated for His sake. All deeds of good should be done to seek His favor and pleasure, and all wrong should be avoided for his sake. In these ways do Muslims worship God alone, and from this, we understand how the whole religion of Islam is based upon this Declaration of Tawhid.
But by a mere verbal pronouncement alone, one does not become a complete Muslim. To become a complete Muslim one has to fully carry out in practice the instruction given by Prophet Muhammad as ordained by God. This brings us to the second part of the testimony.
2. Muhammad is the Messenger of God (Allāh).
Muhammad was born in Makkah in Arabia in the year 570 CE. His ancestry goes back to Ishmael, a son of Prophet Abraham. The second part of the confession of faith asserts that he is not only a prophet but also a messenger of God, a higher role also played by Moses and Jesus before him. Like all prophets before him, he was a human being, but chosen by God to convey His message to all humanity rather than one tribe or nation from among the many that exist. For Muslims, Muhammad brought the last and final revelation. In accepting Muhammad as the “last of the prophets,” they believe that his prophecy confirms and completes all of the revealed messages, beginning with that of Adam. In addition, Muhammad serves as the preeminent role model through his life example. The believer’s effort to follow Muhammad’s example reflects the emphasis of Islam on practice and action. 
And Allāh Almighty Knows best.
