Yahya related to me from Malik from Suhayl ibn Abi Salih from his father from Abu Hurayra that the Messenger of Allah ﷺ gave hospitality to a kafir guest. The Messenger of Allah ﷺ ordered a sheep to be brought for him and it was milked. He drank its milk. Then another came, and he drank it. Then another came and he drank it until he had drunk the milk of seven sheep. In the morning he became muslim, and the Messenger of Allah ﷺ ordered a sheep for him. It was milked and he drank its milk. Then he ordered another for him and he could not finish it. The Messenger of Allah ﷺ said, "The mumin drinks in one intestine, and the kafir drinks in seven intestines."

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