Al-Adab Al-Mufrad, Hadith 112 ⓘ
Ibn 'Abbas told Ibn az-Zubayr, "I heard the Prophet, may Allah bless him and grant him peace, say, 'A man is not a believer who fills his stomach while his neighbour is hungry.'"
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، قَالَ: أَخْبَرَنَا سُفْيَانُ، عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي بَشِيرٍ، عَنْ عَبْدِ اللهِ بْنِ الْمُسَاوِرِ قَالَ: سَمِعْتُ ابْنَ عَبَّاسٍ يُخْبِرُ ابْنَ الزُّبَيْرِ يَقُولُ: سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ: لَيْسَ الْمُؤْمِنُ الَّذِي يَشْبَعُ وَجَارُهُ جَائِعٌ.
