Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) said: When the Messenger of Allah (peace and blessings be upon him) would raise his head from bowing (ruku‘), he would say: «سَمِعَ اللّٰهُ لِمَنْ حَمِدَهُ، رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَاوَاتِ وَالْاَرْضِ وَمِلْءَ مَا بَيْنَهُمَا وَمِلْءَ مَا شِئْتَ مِنْ شَيْيءٍ بَعْدُ» . Imam Darimi (may Allah have mercy on him) was asked: Do you say this? He replied: No. He was asked: Do you say this in the obligatory prayer? He replied: Almost, and he explained that saying everything (that is narrated) is correct.
