The Qur'an speaks directly against the pagan doctrine of the Trinity

 

Sura 5:73 They do blaspheme who say: Allah is one of three in a Trinity: for there is no god except One Allah. If they desist not from their word (of blasphemy), verily a grievous penalty will befall the blasphemers among them.

​

Sura 4. 171 people of the Book! commit no excesses in your religion: nor say of Allah aught but truth. Christ Jesus the son of Mary was an Apostle of Allah and His Word which He bestowed on Mary and a Spirit proceeding from Him: so believe in Allah and His Apostles. Say not "Trinity": desist: it will be better for you: for Allah is One Allah: glory be to him: (for Exalted is He) above having a son. To Him belong all things in the heavens and on earth. And enough is Allah as a Disposer of affairs

​

Sura 5.72 – 4 They do blaspheme who say: "Allah is Christ the son of Mary." But said Christ: "O children of Israel! worship Allah my Lord and your Lord." Whoever joins other gods with Allah, Allah will forbid him the garden and the Fire will be his abode. There will for the wrong-doers be no one to help.

​

Sura 112:1 Say: He is Allah, the One and Only;

​

Sura 112:2 Allah, the Eternal, Absolute;

Sura 112:3 He begetteth not, nor is He begotten;

​

Sura 6:101 To Him is due the primal origin of the heavens and the earth: how can He have a son when He hath no consort? He created all things and He hath full knowldedge of all things.

​

Sura 72.3 And exalted is the Majesty of our Lord: He has taken neither a wife nor a son.
