Al-Aswad bin Qays said: I heard Sayyiduna Jundub (may Allah be pleased with him) say that the Prophet (peace and blessings be upon him) fell ill, and he (peace and blessings be upon him) did not stand in prayer for a night or two. A woman came and said: "O Muhammad, I think (Allah forbid) that your devil has abandoned you." So Allah Almighty revealed these verses: "By the morning brightness, and by the night when it covers with stillness, your Lord has not forsaken you, nor is He displeased" [Surah al-Duha: 1-3].

Al-Aswad said: I heard Jundub (may Allah be pleased with him) say that the Prophet (peace and blessings be upon him) fell ill, and he (peace and blessings be upon him) did not stand in prayer for two or three nights. A woman said: "O Muhammad, I hope that your devil has abandoned you (Allah forbid); I have not seen him near you for two or three nights." So Allah revealed these verses: "By the morning brightness, and by the night when it covers with stillness. Your Lord has not forsaken you, nor is He displeased" [Surah al-Duha: 1-3].

Abdullah bin Abi Musa al-Nasri said that Sayyidah Aishah (may Allah be pleased with her) said to me: "Do not abandon standing in prayer at night, for the Prophet (peace and blessings be upon him) never abandoned it. When he (peace and blessings be upon him) was ill or weak, he would pray sitting."
