Anas narrated: "We used to hope that an intelligent Bedouin would show up to question the Prophet while we were with him. So one while we were with him, a Bedouin came, kneeling in front of the Prophet, and he said: 'O Muhammad, your messenger came to us and told us that you say that Allah sent you.' So the Prophet say: 'Yes.' He said, 'So, (swear) by the One who raised the heaves, and spread out the earth, and erected the mountains; has Allah sent you?' The Prophet said, 'Yes.' He said: 'Your messenger told us that you say that there are five prayers required from us in a day and a night.' The Prophet said, 'Yes.' He said, 'By the One Who sent you, has Allah ordered that you you?' He said, 'Yes.' He said, 'Your messenger told us that you say that we are required to fast for a month out of the year.' He said, 'He told the truth.' He said, 'By the One Who sent you, has Allah ordered that you?' The Prophet said, 'Yes.' He said, 'Your messenger told us that Zakat is required from our wealth.' The Prophet said, 'He told the truth.' He said, 'By the One Who sent you, has Allah ordered you that?' The Prophet said, 'Yes.' He said, 'Your messenger told us that you say that we are required to perform Hajj to Allah's House if able to undertake the journey.' The Prophet said, 'Yes.' He said, 'By the One Who sent you, has Allah Commanded you that?' (The Prophet said:) 'Yes.' So he said: 'By the One Who sent you with the Truth, I will not leave any of them, nor surpass them.' Then he got up quickly (leaving). The Prophet said: 'If the Bedouin told the truth, then he will enter Paradise.'"
