حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ ، حَدَّثَنَا عَبْدُ الْوَارِثِ ، حَدَّثَنَا أَبُو التَّيَّاحِ ، حَدَّثَنِي أَبُو عُثْمَانَ النَّهْدِيُّ ، عَنْ أَبِي هُرَيْرَةَ ، قَالَ : " أَوْصَانِي خَلِيلِي صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِثَلَاثٍ ، بِصِيَامِ ثَلَاثَةِ أَيَّامٍ مِنْ كُلِّ شَهْرٍ ، وَرَكْعَتَيِ الضُّحَى ، وَأَنْ أُوتِرَ قَبْلَ أَنْ أَرْقُدَ " .
Abu Hurairah (RA) reported. My friend (the Holy Prophet, may peace be upon him) has instructed me to do three things: three fasts during every month, two rak'ahs of the forenoon prayer, and observing Witr prayer before going to bed.
