Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "Allah, the Exalted, says: 'I have no reward other than Jannah for a believing slave of Mine who remains patient for My sake when I take away his beloved one from among the inhabitants of the world".

[Al-Bukhari].

وعن أبي هريرة رضي الله عنه أن رسول الله ﷺ قال : " يقول الله تعالى : ما لعبدي المؤمن عندي جزاء إذا قبضت صفيه من أهل الدنيا ثم احتسبه إلا الجنة" ((رواه البخاري)).
