'Amr bin Taghlib (May Allah be pleased with him) reported:
Some booty or prisoners of war were brought to Messenger of Allah (ﷺ) and he distributed them, giving some men and neglecting others. Then, he was informed that those whom he had not given a thing were displeased. On this the Messenger of Allah (ﷺ) praised Allah and glorified Him and said, "It is a fact that I give to one and overlook another. The one I ignore is dearer to me than the one I give. I give to those in whose hearts I perceive anxiety; others I leave with the richness and contentment that Allah has put in their hearts. One of them is 'Amr bin Taghlib." Upon this 'Amr bin Taghlib said, "By Allah I shall not accept a herd of red camels in exchange for what the Prophet said (about me)."[Al-Bukhari].
