What did Prophet Muhammad (saw) do after he woke up in the night to perform prayer?
 Narrated `Abdullah bin `Abbas:                     That he stayed overnight in the house of Maimuna the wife of the Prophet, his aunt. He added : I lay on the bed (cushion transversally) while Allah's Apostle and his wife lay in the lengthwise direction of the cushion. Allah's Apostle slept till the middle of the night, either a bit before or a bit after it and then woke up, rubbing the traces of sleep off his face with his hands. He then, recited the last ten verses of Sura Al-`Imran, got up and went to a hanging water-skin. He then Performed the ablution from it and it was a perfect ablution, and then stood up to offer the prayer. I, too, got up and did as the Prophet had done. Then I went and stood by his side. He placed his right hand on my head and caught my right ear and twisted it. He prayed two rak`at then two rak`at and two rak`at and then two rak`at and then two rak`at and then two rak`at (separately six times), and finally one rak`a (the witr). Then he lay down again in the bed till the Mu'adh-dhin came to him where upon the Prophet got up, offered a two light rak`at prayer and went out and led the Fajr prayer.
