Hadith on Witr: Pray witr at beginning, but end of night is better

Jabir reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever fears he cannot stand for prayer at the end of the night, let him perform witr prayer in its beginning. Whoever hopes to stand for prayer at the end of the night, let him perform witr prayer at its ending. Verily, prayer at the end of the night is witnessed, and that is better.

عَنْ جَابِرٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ خَافَ أَنْ لَا يَقُومَ مِنْ آخِرِ اللَّيْلِ فَلْيُوتِرْ أَوَّلَهُ وَمَنْ طَمِعَ أَنْ يَقُومَ آخِرَهُ فَلْيُوتِرْ آخِرَ اللَّيْلِ فَإِنَّ صَلَاةَ آخِرِ اللَّيْلِ مَشْهُودَةٌ وَذَلِكَ أَفْضَلُ
