باب تَحْرِيمِ الاِحْتِكَارِ فِي الأَقْوَاتِ ‏‏
Sahih Muslim 1605 a

Ma`mar (Allah be pleased with him) reported Allah's Messenger (ﷺ) 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 ‏.‏
