We went along with Messenger of Allah ( ﷺ) to visit a person suffering from fever. When I placed my hand upon him, I said: By Allah, I have never seen, till this day, a person running higher temperature than he. Thereupon Allah's Apostle ( ﷺ), turning his face to his companions, said: May I not inform you of a severer temperature than this which these two persons would run on the Day of Resurrection? And they were two hypocrites riding upon the camel turning their back towards (the Muslims).
عُدْنَا مَعَ رَسُولِ اللَّهِ ﷺ رَجُلاً مَوْعُوكًا قَالَ فَوَضَعْتُ يَدِي عَلَيْهِ فَقُلْتُ وَاللَّهِ مَا رَأَيْتُ كَالْيَوْمِ رَجُلاً أَشَدَّ حَرًّا فَقَالَ نَبِيُّ اللَّهِ ﷺ أَلاَ أُخْبِرُكُمْ بِأَشَدَّ حَرًّا مِنْهُ يَوْمَ الْقِيَامَةِ هَذَيْنِكَ الرَّجُلَيْنِ الرَّاكِبَيْنِ الْمُقَفِّيَيْنِ لِرَجُلَيْنِ حِينَئِذٍ مِنْ أَصْحَابِهِ
