Abdullah bin Abi Qais reports: I asked Umm al-Mu’minin Sayyida Aisha (may Allah be pleased with her) about the recitation of the Messenger of Allah (peace and blessings be upon him): Did he recite (in the night prayer) quietly or aloud? She replied: He would recite in both ways. Sometimes he would recite in a low voice and sometimes he would recite aloud. I said: All praise is due to Allah, Who has granted great breadth and ease in matters of religion.
