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.'"
