وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «توضؤوا مِمَّا مَسَّتِ النَّارُ» . رَوَاهُ مُسْلِمٌ قَالَ الشَّيْخُ الإِمَام الْأَجَل محيي السّنة: هَذَا مَنْسُوخ بِحَدِيث ابْن عَبَّاس: قَالَ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَكَلَ كَتِفَ شَاةٍ ثُمَّ صلى وَلم يتَوَضَّأ
English Translation
Abu Huraira said that he heard God’s messenger say, “Perform ablution because of anything which has been touched by fire.” Muslim transmitted it. The illustrious shaikh and imam Muhyi as-Sunna said that this is abrogated by the tradition of Ibn ‘Abbas who said that God’s messenger ate a shoulder of mutton, then prayed without performing ablution. (Bukhari and Muslim.)
