Sayyiduna Jarir (may Allah be pleased with him) narrates: I pledged allegiance to the Noble Prophet (peace and blessings be upon him) on his blessed hand for obedience and submission, and for wishing well for every Muslim. (The narrator says) It was his (i.e., the Noble Prophet’s or perhaps Sayyiduna Jarir’s) practice that when he would buy or sell something, the other party would say: Know this, that what we have obtained from you is dearer to us than what we have given you, so now you have the choice (i.e., you may complete the transaction).
