"My dearest friend advised me (to do) three things: 'To sleep after praying Witr, to fast three days each month, and to pray two rak'ahs of Fajr.'" (Using translation from Nasāʾī 1677)
أَوْصَانِي خَلِيلِي ﷺ بِثَلَاثٍ «النَّوْمِ عَلَى وِتْرٍ وَصِيَامِ ثَلَاثَةِ أَيَّامٍ مِنْ كُلِّ شَهْرٍ وَرَكْعَتَيِ الضُّحَى» خَالَفَهُ مُحَمَّدُ بْنُ جَعْفَرٍ
