Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّزَّاقِ حَدَّثَنَا مَعْمَرٌ عَنِ الزُّهْرِيِّ عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا قَالَ الْإِمَامُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا وَلَكَ الْحَمْدُ.
English Translation
Abd al-Razzaq told us, Ma'mar told us, from al-Zuhri, from Anas ibn Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "When the imam says, 'Allah hears whoever praises Him,' then say, 'Our Lord, and to You is the praise.'"
