[Machine] I saw people in the time of the Messenger of Allah ﷺ when they exchanged food, they would strike a deal to sell their places until they found shelter in their tents.
رَأَيْتُ النَّاسَ فِي عَهْدِ رَسُولِ اللهِ ﷺ إِذَا تَبَايَعُوا الطَّعَامَ جُزَافًا يُضْرَبُونَ فِي أَنْ يَبِيعُوا مَكَانَهُمْ حَتَّى يُؤْوُوهُ إِلَى رِحَالِهِمْ
