Tawheed of Allah (Oneness of Allah) in the Holy Quran

(255) Allah - there is no deity except Him, the Ever-Living, the Sustainer of [all] existence. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is [presently] before them and what will be after them, and they encompass not a thing of His knowledge except for what He wills. His Kursi extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great.

(2) Allah - there is no deity except Him, the Ever-Living, the Sustainer of existence.

(26) Say, "O Allah, Owner of Sovereignty, You give sovereignty to whom You will and You take sovereignty away from whom You will. You honor whom You will and You humble whom You will. In Your hand is [all] good. Indeed, You are over all things competent.

(18) And He is the subjugator over His servants. And He is the Wise, the Acquainted [with all].

(56) Say, "Indeed, I have been forbidden to worship those you invoke besides Allah." Say, "I will not follow your desires, for I would then have gone astray, and I would not be of the [rightly] guided."

(161) Say, "Indeed, my Lord has guided me to a straight path - a correct religion - the way of Abraham, inclining toward truth. And he was not among those who associated others with Allah."

(163) No partner has He. And this I have been commanded, and I am the first [among you] of the Muslims."

(164) Say, "Is it other than Allah I should desire as a lord while He is the Lord of all things? And every soul earns not [blame] except against itself, and no bearer of burdens will bear the burden of another. Then to your Lord is your return, and He will inform you concerning that over which you used to differ."

(165) And it is He who has made you successors upon the earth and has raised some of you above others in degrees [of rank] that He may try you through what He has given you. Indeed, your Lord is swift in penalty; but indeed, He is Forgiving and Merciful.

(32) For that is Allah, your Lord, the Truth. And what can be beyond truth except error? So how are you averted?

(104) Say, [O Muhammad], "O people, if you are in doubt as to my religion - then I do not worship those which you worship besides Allah; but I worship Allah, who causes your death. And I have been commanded to be of the believers

(105) And [commanded], 'Direct your face toward the religion, inclining to truth, and never be of those who associate others with Allah;

(51) And Allah has said, "Do not take for yourselves two deities. He is but one God, so fear only Me."

(28) That they may understand my speech.

(26) Allah - there is no deity except Him, Lord of the Great Throne."

(30) So direct your face toward the religion, inclining to truth. [Adhere to] the fitrah of Allah upon which He has created [all] people. No change should there be in the creation of Allah. That is the correct religion, but most of the people do not know.

(4) Indeed, your God is One,

(82) Exalted is the Lord of the heavens and the earth, Lord of the Throne, above what they describe.

(84) And it is Allah who is [the only] deity in the heaven, and on the earth [the only] deity. And He is the Wise, the Knowing.

(13) Allah - there is no deity except Him. And upon Allah let the believers rely.

(1) Say, "O disbelievers,

(2) I do not worship what you worship.

(3) Nor are you worshippers of what I worship.

(4) Nor will I be a worshipper of what you worship.

(5) Nor will you be worshippers of what I worship.

(6) For you is your religion, and for me is my religion."

(1) Say, "He is Allah, [who is] One,

(2) Allah, the Eternal Refuge.

(3) He neither begets nor is born,

(4) Nor is there to Him any equivalent."
