It is narrated from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever buries three of his children, and is patient over them and hopes for reward, Paradise becomes obligatory for him." Sayyidah Umm Ayman (may Allah be pleased with her) said: "Or two?" He (peace and blessings be upon him) said: "Whoever buries two, and is patient over them and hopes for reward, Paradise becomes obligatory for him too." Sayyidah Umm Ayman (may Allah be pleased with her) said: "Or one?" The narrator said: He (peace and blessings be upon him) remained silent, or held back.
(The narrator) said: I heard Sayyidah Umm Ayman (may Allah be pleased with her) say: "Whoever buries one, and is patient and hopes for reward, Paradise is his as well."
