Hadith 3:40
Abu Rafi' said, “I testify that I was roasting the inside of a sheep for God’s messenger, then he prayed without performing ablution.” Muslim transmitted it.
عَن أبي رَافع قَالَ: أَشْهَدُ لَقَدْ كُنْتُ أَشْوِي لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَطْنَ الشَّاةِ ثُمَّ صلى وَلم يتَوَضَّأ. رَوَاهُ مُسلم
