Sa‘d b. Abu Waqqas said:While I was sitting God’s Messenger gave a company something but omitted the one who was most attractive to me. I therefore got up and said, ‘Why have you omitted so and so? I swear by God that I consider him to be a believer.” God’s Messenger replied, “No, a Muslim.” Sa'd mentioned that three times and he gave him the same reply, then said, “I give a man something although I like someone else better, from fear he may be thrown face downwards in hell.” (Bukhari and Muslim.) In a version by both of them Zuhri said be considered that Islam is the attestation of belief and faith is good action.
