Saying: “Truly! We are witnesses to this” by the Imam upon finishing the recitation of Surah Al-Tin

Q: An Imam (the one who leads congregational Prayer) recites Surah (Qur'anic chapter) Al-Tin while performing Maghrib (Sunset) Prayer and after reciting (Part No. 5; Page No. 343) the last Ayah (Qur’anic verse) of it: Is not Allâh the Best of judges? He says loudly: “Truly! We are witnesses to this.” Is their any textual proof for the foregoing? Is whoever does so considered sinful?

A: No authentic proof is reported from the Prophet (peace be upon him) to the effect that what is mentioned in the question or anything else is to be said after the recitation of Surah Al-Tin. It is thus Wajib (obligatory) to abandon such a saying for the Prophet (peace be upon him) said: “Anyone who does an action which is not in accordance with this matter of ours (Islam) will have it rejected.” May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
