It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: When a person dies, all his deeds come to an end except for three: (1) ongoing charity, (2) knowledge from which benefit is derived, and (3) a righteous child who prays for him.

It is narrated from Sayyiduna Abu Umamah Bahili (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Four types of people continue to receive reward even after their death: (1) The person who died while guarding in the way of Allah, (2) The person who teaches knowledge to people, so as long as it is acted upon, he will continue to receive reward, (3) The person who gives charity, so as long as people benefit from it, he will continue to receive reward, and (4) The person who leaves behind righteous children who continue to pray for him.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When Allah Almighty elevates the rank of a righteous servant in Paradise, he will ask: O my Lord! How did I attain this rank? Allah Almighty will say: Because of your son's supplication for your forgiveness.

Sayyiduna Mu’adh (may Allah be pleased with him) narrates that the Messenger of Allah said: If a person constructs a building without injustice or excess, or plants a tree without injustice or excess, then as long as Allah’s creation continues to benefit from it, he will continue to receive reward.

Narrated by Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever uses his tongue for such a good deed that continues to be acted upon after him, Allah Almighty will continue to reward him until the Day of Resurrection, and on the Day of Resurrection, He will grant him the full reward.
