English translation
796. Narrated Abū Hurairah رضي الله عنه: Allāh's Messenger ﷺ said, "When the Imām says, Sami' Allāhu liman ḥamida (Allāh heard those who sent praises and thanks to Him), you should say, Allāhumma Rabbanā lakal-ḥamd (O Allāh! Our Lord! All the praises and thanks are for You). And if the saying of any one of you coincides with that of the angels, all his past sins will be forgiven."
