Ibn Mas'ud (May Allah be pleased with him) reported:
After the battle of Hunain, Messenger of Allah (ﷺ) favoured some people in the distribution of spoils (for consolation). He gave Al-Aqra' bin Habis and 'Uyainah bin Hisn a hundred camels each and showed favour also to some more honourable persons among the Arabs. Someone said: "This division is not based on justice and it was not intended to win the Pleasure of Allah." I said to myself: "By Allah! I will inform Messenger of Allah (ﷺ) of this." I went to him and informed him. His face became red and he said, "Who will do justice if Allah and His Messenger do not?" Then he said, "May Allah have mercy on (Prophet) Musa (Moses); he was caused more distress than this but he remained patient." Having heard this I said to myself: "I shall never convey anything of this kind to him in future".[Al-Bukhari and Muslim].
