He who hoards is a sinner. It was said to Saʿid (b. al-Musayyib): You also hoard. Saʿid said: Maʿmar who narrated this hadith also hoarded. (Using translation from Muslim 1605a)   

قَالَ رَسُولُ اللهِ ﷺ مَنِ احْتَكَرَ فَهُوَ خَاطِئٌ فَقَالَ إِنْسَانٌ لِسَعِيدٍ فَإِنَّكَ تَحْتَكِرُ فَقَالَ سَعِيدٌ مَعْمَرٌ الَّذِي كَانَ يُحَدِّثُ هَذَا الْحَدِيثَ كَانَ يَحْتَكِرُ  

[Machine] The Messenger of Allah ﷺ said, "No one hoards except a sinner." So, I said to Sa'id, "Indeed, you hoard." He said, "And Ma'mar used to hoard the wording of the hadith of Abu Abdullah, but there is no reporting of Ibn Abdan by the sons of Adi ibn Ka'b." And he added at the end, "Amr said, 'Sa'id used to hoard oil.'"  

قَالَ رَسُولُ اللهِ ﷺ لَا يَحْتَكِرُ إِلَّا خَاطِئٌ فَقُلْتُ لِسَعِيدٍ فَإِنَّكَ تَحْتَكِرُ قَالَ وَمَعْمَرٌ كَانَ يَحْتَكِرُ لَفْظُ حَدِيثِ أَبِي عَبْدِ اللهِ وَلَيْسَ فِي رِوَايَةِ ابْنِ عَبْدَانَ أَحَدِ بَنِي عَدِيِّ بْنِ كَعْبٍ وَزَادَ فِي آخِرِهِ قَالَ عَمْرٌو كَانَ سَعِيدٌ يَحْتَكِرُ الزَّيْتَ  

[Machine] The Messenger of Allah ﷺ said: "Whoever hoards intending to overcharge the Muslims, he is in error and has been discharged from the protection of Allah."  

قَالَ رَسُولُ اللهِ ﷺ مَنِ احْتَكَرَ يُرِيدُ أَنْ يُغَالِيَ بِهَا عَلَى الْمُسْلِمِينَ فَهُوَ خَاطِئٌ وَقَدْ بَرِئَتْ مِنْهُ ذِمَّةُ اللهِ  

[Machine] I heard the Messenger of Allah ﷺ saying, "Whoever enters into the prices of the Muslims, intending to exploit them, it is obligatory upon Allah to throw him into a portion of Hellfire on the Day of Resurrection."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ دَخَلَ فِي شَيْءٍ مِنْ أَسْعَارِ الْمُسْلِمِينَ لِيُغْلِيَهُ عَلَيْهِمْ كَانَ حَقًّا عَلَى اللهِ أَنْ يَقْذِفَهُ فِي مُعْظَمٍ مِنَ النَّارِ يَوْمَ الْقِيَامَةِ  

[Machine] The Messenger of Allah ﷺ said, "The one who brings goods and resources is blessed, while the one who hoards and monopolizes is cursed." Ali ibn Salim narrated this from Ali ibn Zaid. Al-Bukhari said, "His narration is not considered reliable."  

قَالَ رَسُولُ اللهِ ﷺ الْجَالِبُ مَرْزُوقٌ وَالْمُحْتَكِرُ مَلْعُونٌ تَفَرَّدَ بِهِ عَلِيُّ بْنُ سَالِمٍ عَنْ عَلِيِّ بْنِ زَيْدٍ قَالَ الْبُخَارِيُّ لَا يُتَابَعُ فِي حَدِيثِهِ  

[Machine] "Omar, may Allah be pleased with him, said: Neither long life nor abundant blessings come to us from Allah except when people flourish through their earnings. But when groups come and monopolize trade, they divert themselves from helping widows and the poor. Whenever profits are made, they sell as they please, with no restrictions. However, whatever goods are brought carrying the burden on their back in summer and winter until they are sold in our market, is a provision for Omar. So, let him sell as he pleases by the will of Allah and let him restrain as he pleases by the will of Allah. Malik mentioned this in Al-Muwatta, narrated from Omar ibn Al-Khattab."  

عُمَرُ لَا وَلَا نِعْمَةَ عَيْنٍ يَأْتِينَا اللهُ ﷻ بِالرِّزْقِ حَتَّى إِذَا نَزَلَ بِسُوقِنَا قَامَ أَقْوَامٌ فَاحْتَكَرُوا بِفَضْلِ أَذْهَابِهِمْ عَنِ الْأَرْمَلَةِ وَالْمِسْكِينِ إِذَا خَرَجَ الْجُلَّابُ بَاعُوا عَلَى نَحْوِ مَا يُرِيدُونَ مِنَ التَّحَكُّمِ وَلَكِنْ أَيُّمَا جَالِبٍ جَلَبَ يَحْمِلُهُ عَلَى عَمُودِ كَبِدِهِ فِي الشِّتَاءِ وَالصَّيْفِ حَتَّى يَنْزِلَ سُوقَنَا فَذَلِكَ ضَيْفٌ لِعُمَرَ فَلْيَبِعْ كَيْفَ شَاءَ اللهُ وَلْيُمْسِكْ كَيْفَ شَاءَ اللهُ وَذَكَرَهُ مَالِكٌ فِي الْمُوَطَّأِ مُرْسَلًا عَنْ عُمَرَ بْنِ الْخَطَّابِ ؓ
