Sahih Muslim , Book 10, Hadith 3910 (USC-MSA) ⓘ

Ma`mar (Allah be pleased with him) reported Allah's Messenger as saying: He who hoards is a sinner. It was said to Sa`id (b. al-Musayyib): You also hoard. Sa`id said: Ma`mar who narrated this hadith also hoarded.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ بِلاَلٍ - عَنْ يَحْيَى، - وَهُوَ ابْنُ سَعِيدٍ - قَالَ كَانَ سَعِيدُ بْنُ الْمُسَيَّبِ يُحَدِّثُ أَنَّ مَعْمَرًا، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنِ احْتَكَرَ فَهُوَ خَاطِئٌ ‏" ‏ ‏.‏ فَقِيلَ لِسَعِيدٍ فَإِنَّكَ تَحْتَكِرُ قَالَ سَعِيدٌ إِنَّ مَعْمَرًا الَّذِي كَانَ يُحَدِّثُ هَذَا الْحَدِيثَ كَانَ يَحْتَكِرُ ‏.‏
