It was narrated from Mu’adh bin Jabal that the Prophet said: “By the One in Whose Hand is my soul! The miscarried fetus will drag his mother by his umbilical cord to Paradise, if she (was patient and) sought reward (for her loss).”
حَدَّثَنَا عَلِيُّ بْنُ هَاشِمِ بْنِ مَرْزُوقٍ، حَدَّثَنَا عَبِيدَةُ بْنُ حُمَيْدٍ، حَدَّثَنَا يَحْيَى بْنُ عُبَيْدِ اللَّهِ، عَنْ عُبَيْدِ اللَّهِ بْنِ مُسْلِمٍ الْحَضْرَمِيِّ، عَنْ مُعَاذِ بْنِ جَبَلٍ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ " وَالَّذِي نَفْسِي بِيَدِهِ إِنَّ السِّقْطَ لَيَجُرُّ أُمَّهُ بِسَرَرِهِ إِلَى الْجَنَّةِ إِذَا احْتَسَبَتْهُ " .
