It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) addressed the women and said: "Whoever among you has three children who have died, Allah will admit her to Paradise." The oldest woman among them spoke up and said: "O Messenger of Allah (peace and blessings be upon him)! Will the one who has lost two children also enter Paradise?" The Prophet (peace and blessings be upon him) said: "The one with two (children) will also enter Paradise."
