Volume 2, Book 16, Number 106:
Narrated Ibn ‘Abbas:
Once I passed the night in the house of Maimuna (his aunt). I slept across the bed while Allah’s
Apostle and his wife slept length-wise. The Prophet slept till midnight or nearly so and woke up rub –
bing his face and recited ten verses from Surat “Aal-Imran.” Allah’s Apostle went towards a leather
skin and performed ablution in the most perfect way and then stood for the prayer. I did the same
and stood beside him. The Prophet put his right hand on my head, twisted my ear and then prayed
two Rakat five times and then ended his prayer with Witr. He laid down till the Muadh-dhin came
then he stood up and offered two Rakat (Sunna of Fajr prayer) and then went out and offered the
Fajr prayer.
