حَدَّثَنَا عُمَرُ بْنُ حَفْصِ بْنِ غِيَاثٍ، قَالَ: حَدَّثَنَا أَبِي، عَنْ طَلْقِ بْنِ مُعَاوِيَةَ، عَنْ أَبِي زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ
أَنَّ امْرَأَةً أَتَتِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِصَبِيٍّ فَقَالَتِ: ادْعُ لَهُ، فَقَدْ دَفَنْتُ ثَلَاثَةً، فَقَالَ: احْتَظَرْتِ بِحِظَارٍ شَدِيدٍ مِنَ النَّارِ
A woman came to the Messenger of Allah (sallallahu alayhi wa sallam), may Allah bless him and grant him peace, with a child. She said, “Make supplication for him. I have buried three children.” He said, “You have built a strong barrier against the Fire.”
