Musnad Abi Ya'la 6032 — the Messenger of Allah ﷺ asked: Whom do you

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) asked: "Whom do you count as a 'raqub' among you?" The Companions (may Allah be pleased with them) said: "The one who has no children." He (peace and blessings be upon him) said: "No, rather the (true) raqub is the one who has not sent ahead any child of his (who died in his lifetime, as an advance reward and a provision for the Hereafter)."
