Hadith 19104

حَدَّثَنَا وَكِيعٌ ، حَدَّثَنَا الْأَعْمَشُ ، عَنْ عُبَيْدِ بْنِ الْحَسَنِ الْمُزَنِيِّ ، قَالَ : سَمِعْتُ ابْنَ أَبِي أَوْفَى ، يَقُولُ : كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ ، قَالَ : " سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ ، اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَاءِ وَمِلْءَ الْأَرْضِ ، وَمِلْءَ مَا شِئْتَ مِنْ شَيْءٍ بَعْدُ " . .
It is narrated from Hazrat Ibn Abi Awfa (may Allah be pleased with him) that when the Noble Prophet (peace and blessings be upon him) would raise his head from bowing (ruku), he would say "Sami' Allahu liman hamidah" and then say: "O our Lord Allah! All praise is for You, equal to the fullness of the heavens and the earth, and equal to the fullness of whatever else You will." The previous hadith is also narrated through this second chain of transmission.
