Muwatta Malik, Book 49, Hadith 9 (USC-MSA) ⓘ
Yahya related to me from Malik from Abu'z-Zinad from al-Araj that Abu Hurayra said, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'The muslim eats in one intestine, and the kafir eats in seven!' "
حَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " يَأْكُلُ الْمُسْلِمُ فِي مِعًى وَاحِدٍ وَالْكَافِرُ يَأْكُلُ فِي سَبْعَةِ أَمْعَاءٍ " .
