عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَعَمْرٌو عَنْ يَحْيَى بْنِ جَعْدَةَ ”إِنَّ نَارَكُمْ هَذِهِ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ نَارِ جَهَنَّمَ وَضُرِبَتْ بِالْبَحْرِ مَرَّتَيْنِ وَلَوْلَا ذَلِكَ مَا جَعَلَ اللَّهُ فِيهَا مَنْفَعَةً لِأَحَدٍ“
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: The fire of this world of yours is one seventieth part of the fire of Hell. The fire of Hell was struck upon the sea twice to make it lighter and cooler, and if this had not been done, no person would have been able to benefit from it.
