Mu'adh b. Jabal reported Allah's Messenger ﷺ as saying, “No pair of Muslims will lose three [of their children] by death without Allah bringing them into paradise by His great mercy.” He was asked if that applied if they lost two, and said it did. He was also asked if it applied if they lost one, and said it did. Then he said, “By Him in whose hand my soul is, the abortion draws his mother to paradise by his umbilical cord when she seeks her reward for him from Allah." Ahmad transmitted it, and Ibn Majah transmitted from “By Him in whose hand my soul is."
