Hadith 2:459
Hasan Maqtu' (Al-Albani)
‘Amir said:
The people behind the imam should not say: “Allah listens to him who praises Him.” But they should say: “ Our Lord, to Thee be the praise.”
حَدَّثَنَا بِشْرُ بْنُ عَمَّارٍ، حَدَّثَنَا أَسْبَاطٌ، عَنْ مُطَرِّفٍ، عَنْ عَامِرٍ، قَالَ لاَ يَقُولُ الْقَوْمُ خَلْفَ الإِمَامِ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ وَلَكِنْ يَقُولُونَ رَبَّنَا لَكَ الْحَمْدُ
