that he heard Anas bin Malik say: "While we were sitting in the mosque, a man entered riding a camel; he made it kneel in the mosque, then he hobbled it and said to them: 'Which of you is Muhammad?' The Messenger of Allah (saw) was reclining among them, so they said: 'This fair- skinned man who is reclining.' The man said to him: 'O son of Abdul- Muttalib!' The Prophet (saw) said: 'I am listening to you.' The man said: O Muhammad! I am asking you and will be stern in asking, so do not bear any ill-feelings towards me.' He said: 'Ask whatever you think.' The man said: 'I adjure you by your Lord and the Lord of those who came before you, has Allah sent you to all of mankind?' The Messenger of Allah (saw) said: 'By Allah, yes.; He said: 'I adjure you by Allah, has Allah commanded you to pray the five prayers each day and night?' The Messenger of Allah (saw) said: 'By Allah, yes.' He said: 'I adjure you by Allah, has Allah commanded you to fast this month of each year?' The Messenger of Allah (saw) said: 'By Allah, yes.' He said: 'I adjure you by Allah, has Allah commanded you to take this charity from our rich and distribute it among our poor?' The Messenger of Allah (saw) said: 'By Allah, yes.' The man said: 'I believe in what you have brought, and I am the envoy of my people who are behind me. I am Dimam bin Tha'labah, the brother of Banu Sad bin Bakr.'"
