He reported God’s messenger as saying to some women of the Ansar, “None of you will lose three children by death and seek a reward from God without entering paradise.” One of them asked, “Or two, messenger of God?” He replied, “Or two.” Muslim transmitted it. Bukharl and Muslim have a version which says, “three who were not old enough to sin.”
