Arabic hadith text
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ خَلاَّدٍ الْبَاهِلِيُّ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ وَاقِدِ،
بْنِ مُحَمَّدِ بْنِ زَيْدٍ أَنَّهُ سَمِعَ نَافِعًا، قَالَ رَأَى ابْنُ عُمَرَ مِسْكِينًا فَجَعَلَ يَضَعُ بَيْنَ يَدَيْهِ وَيَضَعُ
بَيْنَ يَدَيْهِ - قَالَ - فَجَعَلَ يَأْكُلُ أَكْلاً كَثِيرًا - قَالَ - فَقَالَ لاَ يُدْخَلَنَّ هَذَا عَلَىَّ فَإِنِّي سَمِعْتُ
رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ "إِنَّ الْكَافِرَ يَأْكُلُ فِي سَبْعَةِ أَمْعَاءٍ "
Translation
Nafi' reported that Ibn 'Umar saw a poor man. He placed food before him and he ate much. He (Ibn 'Umar) said
He should not come to me. for I heard Allah's Messenger (ﷺ) as saying that the non-Muslim eats in seven intestines.
