Ibn Abbas (may Allah be pleased with them both) says: A man came to the Messenger of Allah (peace and blessings be upon him) and spoke with him about some matters, and the man said to the Messenger of Allah (peace and blessings be upon him): Whatever Allah wills and you (will). The Prophet (peace and blessings be upon him) said: "Have you made me equal to Allah? Say: Whatever Allah alone wills."
