Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Allah Almighty named the righteous 'the righteous' (al-abrar) because they treat their fathers, their mothers and their sons well. Just as your parents have a right over you, so too your children have a right over you."
Al-Tabarani recorded it. Its chain contains a narrator, Ubaydullah bin al-Walid al-Wassafi, who is da'if (weak).
