Musannaf Ibn Abi Shaybah

Hazrat Sa’d bin Ubaidah (may Allah have mercy on him) narrates that a man asked Hazrat Ibn Umar (may Allah be pleased with them both): “Tell me about Hazrat Ali (may Allah be pleased with him).” He (may Allah be pleased with him) replied: “Whenever you wish to ask about Hazrat Ali (may Allah be pleased with him), just look at the house near the house of the Messenger of Allah (peace and blessings be upon him). This is his house and this is the house of the Messenger of Allah (peace and blessings be upon him).” The man said: “I have enmity towards him!” He (may Allah be pleased with him) replied: “Then Allah also has enmity towards you.”
