Silsilah Sahihah

A woman from the tribe of Juhaina, Sayyida Qateela bint Saifi (may Allah be pleased with both of them), says: A Jewish scholar came to the Prophet Muhammad (peace and blessings be upon him) and said: "You people commit shirk; you say: (It happens) as Allah wills and as you will. And you also say: By the Ka'bah." The Messenger of Allah (peace and blessings be upon him) said: "You should say: (It happens) as Allah wills and then as you will, and when taking an oath, say: By the Lord of the Ka'bah."
