Mishkat al-Masabih 4 Prayer كتاب الصلاة 299

وَعَنْ عَبْدُ اللَّهِ بْنِ أَبِي أَوْفَى قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا رَفَعَ ظَهْرَهُ مِنَ الرُّكُوعِ قَالَ: «سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَاوَاتِ وَمِلْءَ الْأَرْضِ وَمِلْءَ مَا شِئْتَ من شَيْء بعد» . رَوَاهُ مُسلم

‘Abdallah b. Abu Aufa said that when God’s Messenger raised his back after bowing he said, “God listens to him who praises Him. O God, our Lord, to Thee be the praise in all the heavens and all the earth, and all that it pleases Thee to create afterwards.” Muslim transmitted it.
