عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ضَافَهُ ضَيْفٌ وَهُوَ كَافِرٌ فَأَمَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِشَاةٍ فَحُلِبَتْ فَشَرِبَ حِلَابَهَا ثُمَّ أُخْرَى فَشَرِبَهُ ثُمَّ أُخْرَى فَشَرِبَهُ حَتَّى شَرِبَ حِلَابَ سَبْعِ شِيَاهٍ ثُمَّ إِنَّهُ أَصْبَحَ فَأَسْلَمَ فَأَمَرَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِشَاةٍ فَحُلِبَتْ فَشَرِبَ حِلَابَهَا ثُمَّ أَمَرَ بِأُخْرَى فَلَمْ يَسْتَتِمَّهَا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْمُؤْمِنُ يَشْرَبُ فِي مِعًى وَاحِدٍ وَالْكَافِرُ يشربُ فِي سَبْعَة أمعاء»
In another version by him on the authority of Abu Huraira it says that a man who was an infidel was entertained by God’s messenger. He ordered a sheep to be milked and the man drank what was drawn from it, then another and he drank it, then another and he drank it, till he had drunk the milk drawn from seven sheep. In the morning the man accepted Islam and God’s messenger ordered a sheep to be milked for him . When he had drunk what was drawn from it he ordered another to be milked, but when he did not finish all the milk God’s messenger said, “ The believer drinks in one intestine, but the infidel drinks in seven.”
