المحيط
كلمة (المحيط) في اللغة اسم فاعل من الفعل أحاطَ ومضارعه يُحيط،...
‘Abdullāh ibn ‘Umar (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Whoever buys food, let him not sell it until he receives it in full." Another wording reads: "until takes possession of it."
Because taking possession of the food is something by which the contract is concluded and ownership is fully achieved, the Wise law-giver (Allah) has forbidden the buyer from selling it until he takes possession of it and receives it in full, i.e. becomes under his disposal.
