حَدَّثَنَا ابْنُ أَبِي بُكَيْرٍ هُوَ يَحْيَى حَدَّثَنَا إِبْرَاهِيمُ يَعْنِي ابْنَ نَافِعٍ عَنْ وَهْبِ بْنِ مِينَاسٍ الْعَدَنِيِّ عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا أَرَادَ السُّجُودَ بَعْدَ الرَّكْعَةِ يَقُولُ اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَوَاتِ وَمِلْءَ الْأَرْضِ وَمِلْءَ مَا شِئْتَ مِنْ شَيْءٍ بَعْدُ
مسند امام احمد بن حنبل · Hadith 2505
It was narrated from Ibn 'Abbas (RA) that when the Prophet (PBUH) wanted to prostrate after bowing, he would say: "O Allah our Lord, to You be praise filling the heaven, filling the earth and filling whatever else You will."
