Hadith 4:121
Abu Huraira reported God’s messenger as saying, “Walk quickly at a funeral, for if the dead person was good it is a good condition to which you are sending him on, but if he was otherwise it is an evil of which you are ridding yourselves.” (Bukhari and Muslim.)
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَسْرِعُوا بِالْجَنَازَةِ فَإِنْ تَكُ صَالِحَةً فَخَيْرٌ تُقَدِّمُونَهَا إِلَيْهِ وَإِنْ تَكُ سِوَى ذَلِكَ فشر تضعونه عَن رقابك»
