49:14Al-Hujuraat

The Messenger of Allah distributed (some spoils of war) and gave to some people but withheld from others. I said: "O Messenger of Allah, you gave to so-and-so and so-and-so, and you withheld from so-and-so, who is a beliver." He said: "Do not say 'a believer,' say 'a Muslim.'" Ibn Shihab (one of the narrators) said: The Bedouins say: "We believe".

"When this Ayah was revealed: And whether you disclose what is in yourselves or conceal it, Allah will call you to account for it (2:284). Somethings entered their hearts that had not entered before. So they mentioned that to the Prophet (ﷺ) and he said: 'Say: "We hear and we obey." So Allah put faith into their hearts and Allah Blessed and Most High revealed the Ayah: The Messenger believes in what has been sent down to him from his Lord, and (so do) the believers (and) Allah does not burden a soul beyond what it can bear, for it is what it has earned and against it is what it has wrought. "Our Lord! Punish us not if we forget or fall into error (2:286)." He said: 'I have done so (as requested).' Our Lord! Lay not upon us a burden like that which You did upon those before us. He said: Our Lord! Put not a burden upon us greater than we have strength for. Pardon us and grant us forgiveness. Have mercy on us (2:286). He said: 'I have done so (as requested).'"

"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.'"

The people of the Book used to read the Torah in Hebrew and then explain it in Arabic to the Muslims. Allah's Messenger (ﷺ) said (to the Muslims). "Do not believe the people of the Book, nor disbelieve them, but say, 'We believe in Allah and whatever is revealed to us, and whatever is revealed to you.' "

A bedouin gave the Pledge of allegiance for embracing Islam to Allah's Messenger (ﷺ), and then he got an attack of fever in Medina and came to Allah's Messenger (ﷺ): and said, "O Allah's Messenger (ﷺ)! Cancel my pledge." Allah's Messenger (ﷺ) refused to do so. The bedouin came to him again and said, "Cancel my pledge," but he refused again, and then again, the bedouin came to him and said, "Cancel my pledge," and Allah's Messenger (ﷺ) refused. The bedouin finally went away, and Allah's Messenger (ﷺ) said, "Medina is like a pair of bellows (furnace), it expels its impurities while it brightens and clears its good.'
