Mishkat al-Masabih, 303, 304

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 <i>shaikh</i> and <i>imam</i> 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.)

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
