وَعَنْهُ أَيْضًا قَالَ ثَلَاثٌ أَوْصَانِي بِهِنَّ خَلِيلِي صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا أَدَعُهُنَّ أَبَدًا (وَفِي رِوَايَةٍ لَا أَدَعُهُنَّ حَتَّى أَمُوتَ) الْوِتْرُ قَبْلَ أَنْ أَنَامَ وَصِيَامُ ثَلَاثَةِ أَيَّامٍ مِنْ كُلِّ شَهْرٍ وَالْغُسْلُ يَوْمَ الْجُمُعَةِ
Syedna Abu Hurairah, may Allah be pleased with him, also narrates from this, he says: My beloved friend advised me regarding three matters, I will not abandon them until death: performing Witr before sleeping, fasting three days in every month, and performing Ghusl on the day of Jumu’ah.
