The Dislike of Sleeping After the Fajr Prayer

A Bedouin came to the Prophet صلى الله عليه وعلى آله وسلم and said: "O’ Messenger of Allah صلى الله عليه وعلى آله وسلم, I used to have a strong memory but now I have become forgetful." The Prophet صلى الله عليه وعلى آله وسلم asked: "Did you use to take a midday nap (Qailulah)?" The man replied: "Yes." The Prophet صلى الله عليه وعلى آله وسلم then asked: "And did you stop doing that?" The man answered, "Yes." The Prophet صلى الله عليه وعلى آله وسلم said: "Resume it." The man did so and his memory returned.
