Ibn Uyayna reported,

Muamar said to me that Thawri once asked him, "Have you heard anything regarding a man who stores up provisions for his family for a full year, or for part of a year?"Muamar said, "Nothing came to my mind at the time, but later I recalled a hadith that Ibn Shihab Zuhri narrated to us from Malik bin Aws, from Umar رضي الله عنه, that the Prophet ﷺ used to sell the date palms of Banu Nadir and set aside for his family their provisions for the year."

عن ابن عيينة قال

قال لي معمر قال لي الثوري هل سمعت في الرجل يجمع لأهله قوت سنتهم أو بعض السنة قال معمر فلم يحضرني ثم ذكرت حديثا حدثناه ابن شهاب الزهري عن مالك بن أوس عن عمر رضي الله عنه أن النبي ﷺ كان يبيع نخل بني النضير ويحبس لأهله قوت سنتهم
