It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that a man said to the Prophet (peace and blessings be upon him): "As Allah wills and as you will." The Prophet (peace and blessings be upon him) said: "You have made me a partner and equal with Allah. Rather say: 'As Allah alone wills.'"
