حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَابْنُ أَبِي عُمَرَ، عَنْ عَبْدِ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ قَتَادَةَ، بِهَذَا الإِسْنَادِ وَقَالَ فِي الْحَدِيثِ فَإِنَّ اللَّهَ عَزَّ وَجَلَّ قَضَى عَلَى لِسَانِ نَبِيِّهِ صلى الله عليه وسلم سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ .
This hadith has been transmitted by Qatida with the same chain of transmitters (and the words are): " Allah, the Exalted and the Glorious, commanded it through the tongue of His Messenger (may peace be upon-him): Allah listens to him who praises Him."
