Abu Yunus, who was the freed slave of Hazrat Aisha (may Allah be pleased with her), says: Hazrat Aisha (may Allah be pleased with her) ordered me to write a copy of the Noble Qur'an for her, and she said: When you reach this verse, "Guard strictly the prayers, especially the middle prayer," then inform me. So when I reached there, I informed her. She had me write this verse: "Guard strictly the prayers, especially the middle prayer and the Asr prayer, and stand before Allah with devotion," and she said: I heard this verse from the Prophet (peace and blessings of Allah be upon him) in this way.
