Chapter 47: The Book Of Faith and its Signs
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.'"
