(وَعَنْهُ مِنْ طَرِيقٍ ثَانٍ): قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَأْمُرُنَا بِصِيَامِ اللَّيَالِي الْبِيضِ ثَلَاثَ عَشْرَةَ وَأَرْبَعَ عَشْرَةَ وَخَمْسَ عَشْرَةَ وَقَالَ: ((هِيَ كَصَوْمِ الدَّهْرِ))
(Second chain) He says: The Messenger of Allah, peace and blessings be upon him, commanded us to fast on the white days, that is, the 13th, 14th, and 15th of the lunar month, and said: These are equal to fasting for the whole year.
