It was narrated from 'Amir bin Sa'd bin Abi Waqqas that his father said: The Prophet [SAW] gave a share (of some spoils of war) to some men and not to others. Sa'd said: 'O Messenger of Allah [SAW], you gave to so-and-so and so-and-so, but you did not give anything to so-and-so, and he is a believer.' The Prophet [SAW] said: 'Or a Muslim,' until Sa'd had repeated it three times, and the Prophet [SAW] said: 'I give to some men, and leave those who are dearer to me, without giving them anything, lest (the former) be thrown into Hell on their faces.'
It was narrated from Sa'd that : The Messenger of Allah [SAW] 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 .
It was narrated from Bishr bin Suhaim that: The Prophet [SAW] commanded him to call out on the days of At-Tashriq that no one would enter Paradise except a believer, and that these were the days of eating and drinking.
