Abu Huraira reported that Messenger of Allah ﷺ invited a non-Muslim. Messenger of Allah ﷺ commanded that a goat be milked for him. It was milked and he drank its milk. Then the second one was milked and he drank its milk, and then the other one was milked and he drank its milk. till he drank the milk of seven goats. On the next morning he embraced Islam. And Messenger of Allah ﷺ commanded that a goat should be milked for him and he drank its milk and then another was milked but he did not finish it, whereupon Messenger of Allah ﷺ said: A believer drinks In one intestine whereas a non-believer drinks in seven intestines.

وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا إِسْحَاقُ بْنُ عِيسَى، أَخْبَرَنَا مَالِكٌ، عَنْ سُهَيْلِ بْنِ،
أَبِي صَالِحٍ عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ ضَافَهُ ضَيْفٌ
وَهُوَ 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 فَشَرِبَ حِلاَبَهَا ثُمَّ أَمَرَ بِأُخْرَى فَلَمْ يَسْتَتِمَّهَا فَقَالَ رَسُولُ
اللَّهِ ﷺ
" الْمُؤْمِنُ يَشْرَبُ فِي مِعًى وَاحِدٍ وَالْكَافِرُ يَشْرَبُ فِي سَبْعَةِ أَمْعَاءٍ
" .
