Hadith 1554
He said that the Prophet used to teach them to say when afflicted by fever or any pain, "In the name of God, the Great, I seek refuge in God, the Mighty, from the evil of every vein that bleeds and from the evil of the heat of hell.” Tirmidhi transmitted it, but said this was a gharib tradition which he knew only among the traditions of Ibrahim b. Isma'il who is declared to be weak in tradition.
وَعَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: كَانَ يعلمهُمْ من الْحمى وم الأوجاع كلهَا أَن يَقُولُوا: «بِسم الله الْكَبِيرِ أَعُوذُ بِاللَّهِ الْعَظِيمِ مِنْ شَرِّ كُلِّ عرق نعار وَمن شَرّ حر النَّارِ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ هَذَا حَدِيثٌ غَرِيبٌ لَا يُعْرَفُ إِلَّا مِنْ حَدِيثِ إِبْرَاهِيمَ بْنِ إِسْمَاعِيلَ وَهُوَ يضعف فِي الحَدِيث
