Salih bin Muhammad bin Za'idah said: I was with Maslamah bin Abd al-Malik in the land of the Romans. A man was brought who had committed breach of trust in the spoils of war. He asked Salim about him, and he said: I heard my father narrating from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "If you find a man who has committed breach of trust in the spoils of war, burn his belongings and beat him." The narrator says: We found a copy of the Qur'an among his belongings, and Salim was asked about it. He said: Sell the Qur'an and give its price in charity.
This is weak.
