Allâh, The Almighty, Has Spoken The Truth

Question :

What is the ruling on someone saying "Allâh the Magnificent has Spoken the truth" after reciting the Qur'an?

Answer:

A person saying Sadaq Allahu Al-'Azim "Allah the Magnificent has Spoken the truth" is a statement of praise for Allah Almighty. And such statements of praise are a form of worship, which people are to be rewarded for. For this reason it is not allowed for people to use any form of worship; - no matter what it is except when Allah or His Messenger ﷺ legislated it.

Saying Sadaq Allahu Al-'Azim "Allah the Magnificent has Spoken the truth" upon completion of a recitation of the Qur'an is not allowed, it is not reported from the Prophet ﷺ according to what we know, nor his Companions.

Rather, once Ibn Mas'ud, may Allah be pleased with him, recited Surat An-Nisa' to the Prophet ﷺ. When he reached
"How (will it be) then, when We bring from cach nation a witness and We, bring you (O Muhammad) as a witness against the people."

Then the Prophet ﷺ said :
"(That is) enough for you."

He didn't say, regarding this verse nor any other; "Say: Allah has spoken the truth," nor did he order that, so with this, one should not say it.

Some people think that this phrase is taken from Allah's saying:
"Say: Allah has spoken the truth. So follow the religion of Ibrahim, the upright.

But this is not correct, this is an order from Allah Almighty to the Prophet ﷺ to convey to those who reject Allâh and His Messenger that Allâh verifies the revelation that He reveals to His Messengers.

We do not say to you, O brother Muslim, that you can not say: "Allah the Magnificent has spoken the truth," rather say it, in heart and with your tongue, but do not restrict it to the condition of saying it when finishing recitation of the Qur'an.

It is well known that it is obligatory for people to say, "Allah the Magnificent has Spoken the truth" with the heart and the tongue, and that they believe that there is not anyone more truthful in speech than Allâh, as He said:
"And who is truer in statement than Allah?"

However, this verse is not an evidence for people to say "Allah the Magnificent has Spoken the truth" when finishing their recitation.
