Abu Dawud Book 2, Hadith Number 1375.
Chapter : Lailat alqadr.
Narated By Abdullah ibn Unays al-Juhani : I said to the Apostle of Allah: I have a place in the desert where I live and in which I pray, with the praise of Allah; but give me command about a night when I come to this mosque.
He replied: Come on the twenty third night.
I (a sub-narrator, Muhammad ibn Ibrahim) said to his (Abdullah ibn Unays’s) son: How would your father act?
He replied: He used to enter the mosque when he had offered the afternoon prayer, and did not leave it for any purpose till he prayed the morning prayer. Then when he had prayed the morning prayer, he found his riding beast at the door of the mosque, mounted it and got back to his desert.
