Abu 'Asib said

Allah's Messenger ﷺ went out during the night and when he passed me by and called to me I went out to him. He then passed by Abu Bakr, and when he called him he went out to him. He then passed by 'Umar and when he called him he went out to him. He then set off and when he had entered a garden belonging to one of the Ansar he asked the owner of the garden to give us some ripening dates to eat. He brought a bunch and laid it down, and when he and his companions had eaten he called for some cold water, after drinking which he said, "You will be questioned about this bounty on the day of resurrection." Thereupon 'Umar seized the bunch, and when he had thrown it on the ground so that the ripening dates were scattered towards Allah's Messenger ﷺ he said, " Messenger of Allah , shall we be questioned about this on the day of resurrection?" He replied, "Yes, but not for three things: a rag with which a man covers his private parts, or a crumb with which he allays his hunger, or a shelter 1 into which he warms himself to escape heat and cold." 1. The word is hujr which is basically something forbidden It is then used as a place of protection covered with mud or stone. The following words indicate that something very small is intended. Cf. Mirqat, iv, 397. Pt. 12 Ahmad and Baihaqi, in Shu'ab al-iman, transmitted it.
