It is narrated, most likely as marfu’, from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when he would raise his head from ruku’, after saying «سَمِعَاللّٰهُلِمَنْحَمِدَهُ», he would say: «اَللّٰهُمَّرَبَّنَالَكَالْحَمْدُمِلْءَالسَّمَوَاتِوَمِلْءَالْأَرْضِوَمِلْءَمَاشِئْتَمِنْشَيْءٍبَعْدُ» “O Allah! O our Lord! All praise is for You, which fills the heavens and fills the earth and fills whatever else You will.”
