وَعَنْ ثَوْبَانَ عَنِ
النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ هَذَا السَّهَرَ جُهْدٌ وَثِقَلٌ فَإِذَا أَوْتَرَ أَحَدُكُمْ فَلْيَرْكَعْ رَكْعَتَيْنِ فَإِنْ قَامَ مِنَ اللَّيْلِ وَإِلَّا كَانَتَا لَهُ»
The Prophet (sallallahu alayhi wa sallam) said:, “This wakefulness is a toil and a burden, so when one of you observes a witr he should pray two rakas. If he gets up during the night, well and good; otherwise they will serve for him.”
