Anas bin Malik said: "while we were with the Messenger of Allah, sitting in the Masjid, a man entered on a camel. He made it kneel in the Masjid, then he hobbled it. Then he said; 'Which of you is Muhammad?' He was reclining among them, and we said to him: 'This white man who is reclining.' The man said to him: 'O son of 'Abdul-Muttalib.' The Messenger of Allah said to him: 'I have answered you.' The man said: 'O Muhammad, I am going to ask you questions and I will be harsh in asking.' He said; 'Ask whatever you like.' The man said; 'I adjure you by your Lord, and the Lord of those who came begfore you, has Allah sent you to all the people?' The messenger of Allah said: 'by Allah, yes,' He said: 'Iadjure you by Allah, has Allah commanded you to fast this month each year?' The Messenger of Allah said: 'I adjure you by Allah, has Allah commanded you to take this charity from our rich and divide it among our poor?' The Messenger of Allah said: 'By Allah, Yes.' The ma said; 'I believe in that which you have brought, and I am the envoy of my people who are coming after me. I am Dimam bin Thalabah, the brother of Banu sad bin Bakr."' (Sahih) 'Ubaidullah bin 'Umar contradicted him.

It was narrated that Anas said: "We were forbidden in the Quran to ask the Prophet about anything not imperative, so we liked it when a wise man from among the people of the desert came and asked him. A man from among the desert people came and said: 'O Muhammad, your messenger came to us and told us that you say that Allah, the Mighty and Sublime, has sent you.' He said: 'He spoke the truth.' He said: 'Who created the heavens?' He said: 'Allah.' He said: 'Who created the Earth?' He said: 'Allah.' He said: 'Who set up the mountains in it?' He said: 'Allah.' He said: 'Who created beneficial things in them?' He said: 'Allah.' He said: 'By the One Who created the heavens and the Earth, and set up the mountains therein, and created beneficial things in them, has Allah sent you?' He said: 'Yes.' He said: 'Your messenger said that we have to offer five prayers each day and night.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' He said: 'Yes.' He said: 'Your messenger said that we have to pay Zakah on our wealth.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' He said: 'Yes.' He said: 'Your messenger said that we have to fast the month of Ramadan each year.' He said: 'He spoke the truth.' He said: 'By the One Who sent You, has Allah commanded you to do this?' He said: 'Yes.' He said: 'Your messenger said that we have to perform Hajj, those who can afford it.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' He said: 'Yes.' He said: 'By the One Who sent you with the truth, I will not do more than this or less.' When he left, the Prophet said: 'If he is sincere, he will certainly enter paradise.'"

It was narrated that Anas bin Malik said: "While we were sitting in the Masjid, a man came on a camel and made it keneel in the Masjid, then he hobbled it and said to them: 'Which of you is Muhammad?' The Messenger of Allah was reclining amid his Companions, and we said to him: This white man who is reclining.' The man said to him: 'O son of 'Abdul-Muttalib.' The Messenger of Allah said: ' I have answered you.' The man said; 'O Muhammad, I am going to ask you questions, and I will be harsh in asking; do not get upset.; The man said: 'I adjure you by your Lord and the Lord of those who cam before you, has Allah sent you to all the people?' The Messenger of Allah said: 'By Allah, yes.' He said; 'I adjure you by Allah, has Allah commanded you to offer five prayers each day and night?' The Messenger of Allah said: 'By Allah, yes.; He said: 'I adjure you by Allah, has Allah commanded you to fast this month each year? The Messenger of Allah 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 said. 'By Allah, yes.' The man said: 'I believe in that which you have brought, and I am the envoy of my people who are coming after me. I am Dimam bin Thalabah, the brother of Banu sad bin Bakr."' Yaqub bin Ibrahim contradicted him.
