Ghudaif bin Harith reports: I asked Lady Aisha (may Allah be pleased with her): What do you say about the Prophet (peace be upon him)? Did he recite aloud or in a low voice while praying? Lady Aisha (may Allah be pleased with her) replied: Sometimes he would recite aloud and sometimes in a low voice. So I said: All praise is due to Allah, who has provided flexibility in this matter.
