The entire universe, in the way it is created and the way it is controlled, bears witness to the oneness of Allah: “Surely, His is the creation and commandment. Blessed is Allah, the Lord of the Aalameen (mankind, jinn and all that exists)!” (Qur’an, 7:54)
The creation of the heavens and the earth, the alternation of night and day, the different kinds of inanimate objects, plants and fruits, the creation of humans and animals… all of that indicates that the Almighty Creator is One with no partner or associate: “That is Allah, your Lord, the Creator of all things, La ilaha illa Huwa (none has the right to be worshipped but He). How then are you turning away (from Allah, by worshipping others instead of Him)?” (Qur’an, 40:62)
The variety and greatness of these created things, the perfect way in which they are formed, the way in which they are maintained and controlled, all indicate that the Creator is One and that He does as He wills and rules and decides as He wants:
“Allah is the Creator of all things, and He is the Wakil (Trustee, Disposer of affairs, Guardian) over all things.” (Qur’an, 39:62)
All of the above indicate that this universe has a Creator, that this dominion has a Sovereign, that behind these forms is One Who gives them shape: “He is Allah, the Creator, the Inventor of all things, the Bestower of forms. To Him belong the Best Names.” (Qur’an, 59:24)
The soundness of the heavens and the earth, the order of the universe, the harmony among created things, all indicate that the Creator is One, with no partner or associate: “Had there been therein (in the heavens and the earth) aalihah (gods) besides Allah, then verily, both would have been ruined. Glorified be Allah, the Lord of the Throne, (High is He) above all that (evil) they associate with Him!“(Qur’an, 21:22)
These great created things either created themselves – which is impossible – or man created himself then created them – which is also impossible:
“Were they created by nothing? Or were they themselves the creators? Or did they create the heavens and the earth? Nay, but they have no firm Belief.” (Qur’an, 52:35-36)
Reason, Revelation and the original state of man all indicate that this universe has One Who brought into being, that these created things have a Creator Who is Ever-Living and Eternal, All-Knowing and All-Aware, Powerful and Almighty, Kind and Most Merciful. He has the Most Beautiful Names and Sublime Attributes and He knows all things. Nothing is beyond His control, and there is nothing like unto Him: “And your Ilah (God) is One Ilah (God — Allah), La ilaha illa Huwa (there is none who has the right to be worshipped but He), the Most Gracious, the Most Merciful.” (Qur’an, 2:163)
The existence of Allah is something that is there is no excuse for not knowing. It is the matter of common sense: “Their Messengers said: What! Can there be a doubt about Allah, the Creator of the heavens and the earth?“(Qur’an, 14:10)
Allah has created people with the natural instinct (fitrah) to affirm His Lordship and Oneness, but the shayatin (devils) came to the sons of Adam and caused them to deviate from their religion. According to a Hadith Qudsi, “I created all My slaves as hanifs (monotheists), but the shayaateen (devils) came to them and made them deviate from their religion, and they forbade them that which I had permitted to them.” (Muslim, no. 2865)
Among them are those who deny the existence of Allah, and those who worship the Satan, and those who worship man. And there are those who worship the dinar (money), or fire, or genital organs, or animals. And there are some who associate in worship with Him a stone from the earth or a star in the sky.
These things which are worshipped instead of Allah, cannot create or provide; they cannot hear or see, or bring benefits or cause harm. So how can they worship them instead of Allah?
“Are many different lords (gods) better or Allah, the One, the Irresistible?” (Qur’an, 12:39)
Allah has condemned those who worship these idols which cannot hear, see or think: “Verily, those whom you call upon besides Allah are slaves like you. So call upon them and let them answer you if you are truthful. Have they feet wherewith they walk? Or have they hands wherewith they hold? Or have they eyes wherewith they see? Or have they ears wherewith they hear?” (Qur’an, 7:194-195)
“Say (O Muhammad to mankind): ‘How do you worship besides Allah something which has no power either to harm or benefit you? But it is Allah Who is the All-Hearer, All-Knower.” (Qur’an, 5:76)
How ignorant man is of his Lord Who created him and provides for him. How he rejects Him and forgets Him, and worships others instead of Him: “Verily, it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind.” (Qur’an, 22:46)
Glorified be Allah far above that which they associate with Him. Praise be to Allah the Lord of the Worlds: “Say (O Muhammad): Praise and thanks be to Allah, and peace be on His slaves whom He has chosen (for His Message)! Is Allah better, or (all) that you ascribe as partners (to Him)?“
“Is not He (better than your gods) 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) with Allah? Nay, but they are a people who ascribe equals (to Him)!“
“Is not He (better than your gods) Who has made the earth as a fixed abode, and has placed rivers in its midst, and has placed firm mountains therein, and has set a barrier between the two seas (of salt and sweet water)? Is there any ilah (god) with Allah? Nay, but most of them know not! Is not He (better than your gods) Who responds to the distressed one, when he calls on Him, and Who removes the evil, and makes you inheritors of the earth, generations after generations? Is there any ilah (god) with Allah? Little is that you remember! Is not He (better than your gods) Who guides you in the darkness of the land and the sea, and Who sends the winds as heralds of glad tidings, going before His Mercy (rain)? Is there any ilah (god) with Allah? High Exalted be Allah above all that they associate as partners (to Him)! Is not He (better than your so-called gods) Who originates creation, and shall thereafter repeat it, and Who provides for you from heaven and earth? Is there any ilah (god) with Allah? Say: ‘Bring forth your proofs, if you are truthful.’” (Qur’an, 27:59-64)
