Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "When a man dies, his deeds come to an end except for three things: Sadaqah Jariyah (ceaseless charity), a knowledge which is beneficial, or a virtuous descendant who prays for him (for the deceased)."

[Muslim].

وعنه قال: قال رسول الله ﷺ : "إذا مات ابن آدم انقطع عمله إلا من ثلاث: صدقة جارية ،أو علم ينتفع به، أو ولد صالح يدعو له" ((رواه مسلم)).
