Saying "Truthful is Allah the Exalted" after recitation

Question:
The following message was received by the program from Buraydah in the Qasim region. It is from our brother Abdullah al-Amri. Our brother asks two questions. In his first question, he says: What is the ruling on the phrase "Truthful is the Great Allah" at the end of every recitation?

Answer:
People have become accustomed to this phrase today on the radio and everywhere. It likely has no basis, but if it is sometimes used when it becomes a habit, it is easy to write. If one recites and says "Truthful is the Great Allah" without it being a habit, rather meaning that he is surprised by the speech of Allah and knows that it is the truth, then he says this in the context of affirming Allah’s truthfulness and that the speech is the truth and veracity. There is nothing wrong with that. However, making it a customary closing for every recitation has no basis; rather, it is closer to a religious innovation (bid'ah). If it is made a habit, it is closer to a religious innovation, because the Companions did not do this, and the Prophet (peace and blessings be upon him) did not do this. Even if it was not transmitted, if someone had done it, it would have been transmitted. Since it was not transmitted, that indicates it was not practiced. The good lies in following him and proceeding on the path of Banu Hashim. So, whoever introduces something that the Messenger of Allah (peace and blessings be upon him) and the Companions did not do in a matter of religion is considered an innovation. In any case, regarding this phrase, we do not know that it has a basis. Rather, we see that leaving it is what should be done. As for doing it occasionally, it does no harm.
