Is it better, when standing in night prayer, for a person to stand in the first part of the night or in the last part?

Question:
May Allah reward you. Honorable Shaykh, this questioner says: Is it better for one who cannot stand in the last part of the night, but is able to be consistent in praying in the first part of the night, to be consistent in the first part or in the last part?

Answer:
The scholars said that whoever is confident he will stand in the last part of the night, that is better. As for the one who is not confident he will stand, he prays in the first part of the night. For this reason, the Prophet (peace and blessings be upon him) ordered Abu Hurayrah to pray witr before he sleeps, because Abu Hurayrah (may Allah be pleased with him) would stay up late to memorize hadith, then sleep late and not stand in the last part of the night. So the Prophet (peace and blessings be upon him) advised him to pray witr before he sleeps.
