It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when he would raise his head from bowing and when he intended to go into prostration, he would say: «اَللّٰهُمَّ رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَوَاتِ وَمِلْءَ الْأَرْضِ وَمِلْءَ مَا شِئْتَ مِنْ شَيْءٍ بَعْدُ» "O Allah! O our Lord! All praise is for You, which fills the heavens and fills the earth, and fills whatever else You will."
