عَنْ صَفْوَانَ بْنِ يَعْلَى عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ الْبَحْرُ هُوَ جَهَنَّمُ قَالُوا لِيَعْلَى فَقَالَ أَلَا تَرَوْنَ أَنَّ اللَّهَ عَزَّ وَجَلَّ يَقُولُ {نَارًا أَحَاطَ بِهِمْ سُرَادِقُهَا} [سورة الكهف: 29] قَالَ لَا وَالَّذِي نَفْسُ يَعْلَى بِيَدِهِ لَا أَدْخُلُهَا أَبَدًا حَتَّى أُعْرَضَ عَلَى اللَّهِ عَزَّ وَجَلَّ وَلَا يُصِيبُنِي مِنْهَا قَطْرَةٌ حَتَّى أَلْقَى اللَّهَ عَزَّ وَجَلَّ
It is narrated from Sayyidina Ya'la (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) said: The sea is Hell itself. People said to Sayyidina Ya'la (may Allah be pleased with him): Do you not see that Allah Almighty has said: For the wrongdoers, We have prepared a fire whose canopies will enclose them. (: Surah Al-Kahf: 29) He said: No, by the One in whose hand is Ya'la's soul! I will never enter it until I am presented before Allah Almighty, and not a single drop of it can reach me until I meet Allah Almighty.
