A man who pledges something: who bears its upkeep?

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A pledged item may be ridden, and its milk may be drunk, and the one who drinks the milk and rides is responsible for its upkeep."

Al-Sha'bi was asked about a pledged slave, and he said: "His upkeep is the responsibility of the pledger."

Sufyan says that the upkeep of a pledge is the responsibility of the pledger.

Hasan bin Salih says that the upkeep of a pledge is the responsibility of the pledgee, because it is under his liability.

The view of Abu Hanifah is that it is the responsibility of the pledger.

Yahya bin Adam says: I asked Sharik, "If an animal is given in pledge, who is responsible for its upkeep?" He said: "The pledger."

Al-Rabi' says: I asked Abu Ja'far (may Allah have mercy on him): "I bought food from a man, and he gave me part of it. Then his food ran out and he had nothing left to give me. He said: 'Sell me some of your food so that I can give you (the rest of your share).'" Abu Ja'far said: "Do not even go near this; this is open usury (riba)."
