Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) said: A man had deliberately killed his slave. He was brought to the Prophet (peace and blessings be upon him), who gave him a hundred lashes, banished him for a year, removed his share among the Muslims, and did not take retaliation from him.
