Narrated Mamar bin Abi Mamar, one of the children of Adi bin Kab: The Messenger of Allah ﷺ as saying: No one withholds goods till their price rises but a sinner. I said to Saeed (b. al-Musayyab): You withhold goods till their price rises. He said: Mamar used to withhold goods till their price rose. Abu Dawud said: I asked Ahmad (b. Hanbal): What is hoarding (hukrah) ? He replied: That on which people live. Abu Dawud said: Al-Auzai said: A muhtakir (one who hoards) is one who withholds supply of goods in the market.

Qatadah said: Hoarding does not apply to dried dates. Ibn al-Muthanna said that he (Yahya bin Fayyad) reported on the authority of al-Hasan. We (Ibn al-Muthanna) said to him (Yahya): Do not say: "on the authority of al-Hasan. " Abu Dawud said: This tradition according to us is false. Abu Dawud said: Saeed bin al-Musayyab used to hoard kernel, fodder, and seeds. Abu Dawud said: I heard Ahmad bin Yunus say: I asked Sufyan about hoarding fodder. He replied: They (the people in the past) disapproved of hoarding. I asked Abu Bakr bin Ayyash (about it). He replied: Hoard it.
