Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said: "Allah, the Exalted, says: 'I have no reward except Jannah for a believing slave of Mine who shows patience and anticipates My reward when I take away his favourite one from the inhabitants of the world."'[Al-Bukhari].
