Silsilah as-Sahihah 2491 — Blessings of children's prayers for parents

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, the rank of a man is elevated in Paradise, and he says, 'How did I attain this?' It is said (in reply): 'Because of your child's seeking forgiveness for you.'"
