The Companions of the Messenger of Allah (ﷺ) were pleased to see him. He said: I have come so that I may follow you and get a share from the booty. The Messenger of Allah (ﷺ) said to him: Do you believe in Allah and His Apostle? He said: No. The Messenger of Allah (ﷺ) said: Go back, I will not seek help from a Mushrik (polytheist).

The man returned and overtook him at Baida'? He asked him as he had asked previously: Do you believe in Allah and His Apostle? The man said: Yes. The Messenger of Allah (ﷺ) said to him: Then come along with us.
