Jabir reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: If anyone is afraid that he may not get up in the latter part of the night, he should observe Witr in the first part of it; and if anyone is eager to get up in the last part of it, he should observe Witr at the end of the night, for prayer at the end of the night is witnessed (by the angels) and that is preferable.

Jabir reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: He who amongst you is afraid that he may not be able to get up at the end of the night should observe Witr (in the first part) and then sleep, and he who is confident of getting up and praying at night (i. e. Tahajjud prayer) should observe it at the end of it, for the recitation at the end of the night to visited (by angels), and that is excellent.
