"So-and-so sent me to you to collect such-and-such," and the man gave it to him, believing him. Later, he met the original person and said: "Your messenger came to me, and I sent with him such-and-such," but the man replied: "I did not send him to you, nor did anyone bring me anything." The supposed messenger then claimed that he had indeed been sent and had delivered the item to him. Imam (as) said: "If proof is established against him that he was never sent, his hand is to be cut off. But if there is no proof, the man must swear by Allah (swt) that he did not send him, and the other must recover his money from the messenger." I asked: "What if he claims that necessity compelled him to do so?" Imam (as) replied: "His hand is to be cut off because he has stolen the man's wealth."
