Which is better: performing the witr prayer before sleeping, or delaying it until the end of the night?

Question:
He says: When I pray the 'Isha' prayer, I leave the witr prayer until half an hour before Fajr, and then I pray at that time without lengthening the recitation. Is my action correct?

Answer:
Yes, delaying the witr prayer until the end of the night is better than performing it in the early part of the night. And if you pray whatever is easy for you of the even-numbered voluntary prayers before the witr, that is better. This is better: that you pray whatever is easy for you before the witr. In any case, the witr in the end of the night is better than the witr in the early part of the night.
