Arabic (Original)
حَدَّثَنَا أَبُو النَّضْرِ حَدَّثَنَا الْمُبَارَكُ عَنِ الْحَسَنِ عَنْ أَبِي هُرَيْرَةَ قَالَ أَوْصَانِي خَلِيلِي أَبُو الْقَاسِمِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِثَلَاثٍ لَا أَدَعُهُنَّ صَوْمِ ثَلَاثَةِ أَيَّامٍ مِنْ كُلِّ شَهْرٍ وَأَنْ لَا أَنَامَ إِلَّا عَلَى وِتْرٍ وَالْغُسْلِ يَوْمَ الْجُمُعَةِ.

Abu Hurayrah said: "My close friend Abu al-Qasim (peace be upon him) advised me with three things that I will never abandon: fasting three days of every month, not sleeping except after having prayed Witr, and performing the ritual bath on Friday."
