Ibn Shihab al-Zuhri (may Allah have mercy on him) said that Sayyiduna Uthman bin Affan (may Allah be pleased with him) consulted the noble Companions (may Allah be pleased with them) about the captive. They spoke about it, and Sayyiduna Uthman (may Allah be pleased with him) said: We make someone an heir of Allah's wealth only through proofs.
