Sayyiduna Ibn Abbas (may Allah be pleased with them both) related: Sayyiduna Abbas bin Abd al-Muttalib (may Allah be pleased with him) ordered me to spend the night with the Messenger of Allah (peace and blessings be upon him). So I went to the mosque, and the Messenger of Allah (peace and blessings be upon him) led the people in the Isha prayer, until no one remained in the mosque except him (peace and blessings be upon him). Then he (peace and blessings be upon him) passed by me and said: "Who is this?" I said: Abdullah. He said: "What is the matter?" I said: Abbas has ordered me to stay with you tonight. He said: "Then come along." He said: When he (peace and blessings be upon him) returned home, he said: "Spread a bed for Abdullah." So a pillow of sackcloth was brought for me. He said: Abbas had already told me beforehand: Do not sleep until you have memorised his (peace and blessings be upon him) prayer. He said: Then the Messenger of Allah (peace and blessings be upon him) lay down and slept until I heard the sound of his (peace and blessings be upon him) breathing. Then he (peace and blessings be upon him) sat up straight on his bed, raised his head toward the sky and said three times: "Subhan al-Malik al-Quddus (Glory be to the King, the Most Holy, free of every flaw)." Then he recited this verse at the end of Surah Al Imran, "Indeed, in the creation of the heavens and the earth", up to the end (of the surah). Then he stood up, used the tooth-stick (miswak), performed ablution, then went to his place of prayer and prayed two units (rak'ahs), neither short nor long. Then he returned to his bed and slept until I heard the sound of his (peace and blessings be upon him) breathing. Then he sat up straight on his bed and did as he had done the first time, then used the tooth-stick, performed ablution, then went to his place of prayer and prayed two units, neither long nor short. Then he returned to his bed and slept until I heard the sound of his (peace and blessings be upon him) breathing. Then he sat up straight on his bed and did as he had done before, then prayed, then prayed the Witr. When he (peace and blessings be upon him) finished the prayer, I heard him (peace and blessings be upon him) say: "O Allah, place light in my sight, place light in my hearing, place light in my tongue, place light in my heart, place light on my right, place light on my left, place light in front of me, place light behind me, place light above me, place light beneath me, place light for me on the Day of Resurrection, and make light great for me."
