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].
