Islamic law encourages performing acts of righteousness and obedience. The Muslim is instructed to treat this worldly life as a field in which he plants for his Hereafter. It has clarified that some deeds continue to benefit a person even after death.In this Hadith, Abu Hurayrah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “ Part of what continues to benefit a believer from his deeds and good actions after his death” That is: the impact and reward of these deeds persist beyond the person’s lifetime. This applies broadly to both the righteous and the sinful. However, the Prophet (peace and blessings of Allah be upon him) clarified that what is intended are righteous deeds, when he said: “and good actions after his death.” In other words, the reward continues to reach him. He then gave examples: “Knowledge he taught and spread” — meaning he made it accessible to others by any means, whether through teaching, writing, authoring, or otherwise. “A righteous child he left behind” — and in another version: “a righteous child who prays for him.” Meaning: if the child performs righteous actions taught by the parent, then the parent shares in the reward. “A Mus-haf he bequeathed” — meaning he left behind a copy of the Quran, either as a personal possession or something he endowed for the Muslims. “A mosque he built” — whether through personal effort or financial contribution. “A house he built for a wayfarer” — meaning a shelter or dwelling for travelers. “A canal he caused to flow” — meaning he extracted water, built a means for it to flow, and facilitated its benefit to others. “Charity he gave from his wealth during his lifetime while he was in good health—these continue to reach him after his death” — that is: he gave charity while alive and well, and its reward continues after his passing. Even if some of these actions were not intended to have a lasting effect, Allah out of His Bounty allows any good that benefits people after one’s death, and is a trace of one’s work, to count in one’s record.This Hadith illustrates the immense grace of Allah toward His believing slaves: He has made some deeds continue in reward even after death. It encourages giving Sadaqah Jariyah (ongoing charity) during one’s lifetime, so its benefit endures. It also shows that books of beneficial knowledge left behind are among the righteous deeds whose reward remains after a person’s death..
