Two men who form a partnership and one of them pays

Amr said: I asked Sa'id bin al-Musayyib (may Allah have mercy on him) about two men who were partners. One of them paid the entire price on behalf of his partner. Then they both came to Madinah, sold a portion of the wheat and made a profit, and a portion remained. Then the one who had paid the price said to his partner: "If you wish, pay what remains and stay in your partnership; and if you wish, withdraw from it and from its profit, and I will release you." He said: "This is not lawful."

And I asked al-Qasim, and he said the same.

Salm bin Abi al-Dhayyal said: I asked al-Hasan about two men who bought some goods and then sold them at a profit, partly for cash and partly on credit. Then one of them said to his partner: "Give me my capital, and what remains is yours." He said: Al-Hasan disliked it.
