After reading the Qur'an; is it permissible for us to say: "Truthful is the Mighty Allah"?

The questioner : After reading the Qur'an; is it permissible for us to say: "Truthful is the Mighty Allah"?

The Shaykh : There is no basis for this that the reciters have become accustomed to today, and I have no doubt that it is exactly like the addition of the prayer upon the Prophet (peace and blessings be upon him) after the adhan. As it was said in the philosophy of history: "History repeats itself." And as we all know now, the disagreement that has existed for a long time; when some Islamic preachers began calling for reviving the Sunnah and killing off religious innovation, a very long disagreement arose, and it still continues, unfortunately, although its intensity has decreased over time and as minds have become more enlightened. There was a long disagreement regarding the addition to the adhan, and especially the prayer upon the Messenger (peace be upon him). There is no doubt or ambiguity among the scholars of knowledge that this addition is a religious innovation, but the other people say: this is a good innovation, and the disagreement remains at its peak.
What I want from this introduction is how the matter of this addition after the adhan became such that it is established in the customs of all people—except as Allah wills—that it is part of the adhan? A time will come when their saying today, "Truthful is the Mighty Allah," will become part of... of the Noble Qur'an; because people are accustomed to what they received from their fathers and grandfathers. And if there is a great difference between this addition—"Truthful is the Mighty Allah"—and the prayer upon the noble Prophet; that difference is that there is a verse in the Qur'an that commands the prayer upon the Messenger (peace be upon him); in addition to the hadiths that explicitly state and say: , yet this addition after the adhan is a religious innovation; because it contradicts the teachings of the Messenger (peace be upon him) to his callers like Bilal, Amr ibn Umm Maktum, and Abu Mahdhura. So what do we say about a phrase that has never come in the Shari'ah to be said on any occasion, "Truthful is the Mighty Allah," but rather it is a statement that a person can say on the occasion of citing a verse during a lecture or sermon or the like, saying it at the beginning or the end; he says: "Truthful is the Mighty Allah" in what he said or when he said it, or he recites the verse and says: "Truthful is the Mighty Allah." There is no harm in this on a specific occasion; provided that one does not make it a habit. If this phrase has no basis in the Shari'ah at all, and it is like a word placed in its place on a specific occasion, there is no harm. But committing to it permanently and eternally is undoubtedly a misleading religious innovation, and its ruling is known in the authentic hadith: .
