وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم ضَافَهُ ضَيْفٌ كَافِرٌ فَأَمَرَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم بِشَاةٍ فَحُلِبَتْ فَشَرِبَ حِلاَبَهَا ثُمَّ أُخْرَى فَشَرِبَهُ ثُمَّ أُخْرَى فَشَرِبَهُ حَتَّى شَرِبَ حِلاَبَ سَبْعِ شِيَاهٍ ثُمَّ إِنَّهُ أَصْبَحَ فَأَسْلَمَ فَأَمَرَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم بِشَاةٍ فَحُلِبَتْ فَشَرِبَ حِلاَبَهَا ثُمَّ أَمَرَ لَهُ بِأُخْرَى فَلَمْ يَسْتَتِمَّهَا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ الْمُؤْمِنُ يَشْرَبُ فِي مِعًى وَاحِدٍ وَالْكَافِرُ يَشْرَبُ فِي سَبْعَةِ أَمْعَاءٍ ‏"‏ ‏.‏

Yahya related to me from Malik from Suhayl ibn Abi Salih from hisfather from Abu Hurayra that the Messenger of Allah, may Allah blesshim and grant him peace, gave hospitality to a kafir guest. TheMessenger of Allah, may Allah bless him and grant him peace, ordered asheep to be brought for him and it was milked. He drank its milk. Thenanother came, and he drank it. Then another came and he drank it untilhe had drunk the milk of seven sheep. In the morning he became muslim,and the Messenger of Allah, may Allah bless him and grant him peace,ordered a sheep for him. It was milked and he drank its milk. Then heordered another for him and he could not finish it. The Messenger ofAllah, may Allah bless him and grant him peace, said, "The mumindrinks in one intestine, and the kafir drinks in seven intestines." Translation Not Available
