Hadith 9297ـ وَبِهَذَا الإِسْنَادِ قَالَ ثَلاَثَةٌ يُحْتَجُّ عَلَيْهِمُ الأبْكَمُ وَالطِّفْلُ وَمَنْ مَاتَ فِي الْفَتْرَةِ فَتُرْفَعُ لَهُمْ نَارٌ فَيُقَالُ لَهُمْ ادْخُلُوهَا فَمَنْ دَخَلَهَا كَانَتْ عَلَيْهِ بَرْداً وَسَلاَماً وَمَنْ أَبَى قَالَ تَبَارَكَ وَتَعَالَى هَذَا قَدْ أَمَرْتُكُمْ فَعَصَيْتُمُونِي.
7. Through the same chain of narrators it is said: “Abu ‘Abd Allah (a.s.), has said, ‘An argument will be made against three kinds of people: dumb people, children, and those who have died in the interval between the passing away and coming of a prophet. A fire will be brought before them and they will be commanded to go in it. Those who go in the fire, it will turn cool and peaceful for them. Those who refuse to go in the fire, Allah, the most Blessed, the most High, will say, “Consider, I just commanded you but you disobeyed Me.’””
