Jabir reported God’s Messenger as saying, "If anyone is afraid that he may not get up in the latter part of the night, he should observe a <i>witr</i> in the first part of it; and if anyone is eager to get up in the last part of it he should observe a <i>witr</i> at the end of the night, for prayer at the end of the night is attended by the angels, and that is most excellent.” Muslim transmitted it.

وَعَنْ 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» . رَوَاهُ مُسلم
