Sunan Abi Dawud Book 5, Hadith 105
"And give me abundant light."
Abu Dawud said: This tradition has been transmitted by Abu Khalid al-Dalani from Habib and Salamah b. Kuhail from Abu Rishdin from Ibn 'Abbas in a similar manner.
"In the creation of the heavens and earth" to the end of the surah. Then he stood up and prayed two rak'ahs in which he prolonged the standing, bowing, and prostrations. He then uttered turned away and slept till he bagan to snore. This he did three times. This made six rak'ahs in all. He would use tooth-stick, then perform ablution, and recite those verses. He then observed the witr prayer. The version of 'Uthman has: with three rak'ahs. The mu'adhdhin then came to him and he went out for prayer. The version of Ibn 'Isa adds: He then observed witr prayer ; then Bilal came to him and called him for prayer when the dawn broke. He then prayed the two rak'ahs of the dawn prayer. He then went out for prayer. Then both the narrators were agreed: He beagan to supplicate saying: O Allah, place light in my heart, light in my tongue, light in my hearing, light in my eyesight, light on my right hand, light on my left hand, light in front of me, light behing me, light below me, O Allah, give me abundant light.
I spent a night with the Prophet (ﷺ) to see how he prayed. He got up, performed ablution and prayed two rak'ahs. His standing was like his bowing (i.e. equal in duration), and his bowing was like his prostration (equal in length). Then he slept. Afterwards he awoke, performed ablution, and used tooth-stick. He then recited five verses from Surah Al-'Imran : "In the creation of the heavens and the earth and the alternation of night and day". He went on doing so till he prayed ten rak'ahs. He then stood up and prayed one rak'ah observing witr with it. In the meantime the mu'adhdhin called to prayer. The Messenger of Allah (ﷺ) stood up after the mu'adhdhin had kept silent. He prayed two light rak'ahs and remained sitting till he offered the dawn prayer.
Abu Dawud said: A part of the tradition transmitted by Ibn Bashshar remained hidden from me.
