Abu Yunus, who was the freed slave of Hazrat Aisha (may Allah be pleased with her), says that Hazrat Aisha (may Allah be pleased with her) ordered me to write a copy of the Holy Qur'an for her and said, "When you reach this verse: HAFIZU 'ALAS-SALAWATI WAS-SALATIL WUSTA, inform me." So when I reached there, I informed her. She dictated this verse to me as: HAFIZU 'ALAS-SALATI AL-WUSTA WA SALATI AL-ASR WA QUMU LILLAHI QANITIN, and said, "I heard this verse from the Prophet (peace and blessings be upon him) in this way."
