Narrated Muhammad bin Ibrahim :

From Sa'eed bin Al-Musayyab, from Ma'mar bin 'Abdullah bin Nadlah who said: "I heard the Messenger of Allah ﷺ saying: 'Hoarding is nothing but sin.' So I (Muhammad) said to Sa'eed: "O Abu Muhammad! You hoard?" He said: "And Ma'mar would hoard."

It is also been reported that Sa'eed bin Musayyab would hoard oil, (camel) fodder, and the like.

[Abu 'Eisa said:] There are narrations on this topic from 'Umar, 'Ali, Abu Umamah, and Ibn 'Umar. The Hadith of Ma'mar is a Hasan Sahih Hadith. This is acted upon according to the people of knowledge, they dislike hoarding food, and some of them make a concession for hoarding things other than food. Ibn Al-Mubarak said: "There is no harm in hoarding cotton, goat pelts and like."

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا مُحَمَّدُ بْنُ إِسْحَاقَ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ مَعْمَرِ بْنِ عَبْدِ اللَّهِ بْنِ نَضْلَةَ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " لاَ يَحْتَكِرُ إِلاَّ خَاطِئٌ " . فَقُلْتُ لِسَعِيدٍ يَا أَبَا مُحَمَّدٍ إِنَّكَ تَحْتَكِرُ . قَالَ وَمَعْمَرٌ قَدْ كَانَ يَحْتَكِرُ .

قَالَ أَبُو عِيسَى وَإِنَّمَا رُوِيَ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ أَنَّهُ كَانَ يَحْتَكِرُ الزَّيْتَ وَالْحِنْطَةَ وَنَحْوَ هَذَا .

قَالَ أَبُو عِيسَى وَفِي الْبَابِ عَنْ عُمَرَ وَعَلِيٍّ وَأَبِي أُمَامَةَ وَابْنِ عُمَرَ . وَحَدِيثُ مَعْمَرٍ حَدِيثٌ حَسَنٌ صَحِيحٌ . وَالْعَمَلُ عَلَى هَذَا عِنْدَ أَهْلِ الْعِلْمِ كَرِهُوا احْتِكَارَ الطَّعَامِ . وَرَخَّصَ بَعْضُهُمْ فِي الاِحْتِكَارِ فِي غَيْرِ الطَّعَامِ . وَقَالَ ابْنُ الْمُبَارَكِ لاَ بَأْسَ بِالاِحْتِكَارِ فِي الْقُطْنِ وَالسَّخْتِيَانِ وَنَحْوِ ذَلِكَ .
