وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «من تبع جَنَازَة وحلمها ثَلَاثَ مَرَّاتٍ: فَقَدْ قَضَى مَا عَلَيْهِ مِنْ حَقِّهَا»
Abu Hurayrah reported God’s messenger as saying, “He who follows a bier and carries it three times has accomplished what is ‘due to it from him.’ Tirmidhi transmitted it, saying that this is a gharib tradition. In Sharh as-sunna it is reported that the Prophet (sallallahu alayhi wa sallam) carried the bier of Sad ibn Muadh between the two poles.”
