Sayyiduna Ibn Mas'ud (may Allah be pleased with him) says, the Messenger of Allah (peace and blessings of Allah be upon him) said: "Whom do you count as barren among you?" The people replied: The barren is the one who has no children. He said: "No, rather the barren is the one who has not sent anything ahead from his children." (That is, none of his children died in childhood.)
