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."
