It was narrated from Abu Hurairah that the Prophet ﷺ visited a sick person, due to an illness that he was suffering from and Abu Hurairah was with him. The Messenger of Allah ﷺ said:
“Be of good cheer, for Allah says: ‘It is My fire which I have causes to overwhelm My believing slave in this world, to be his share of the Fire in the Hereafter.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ، عَنْ إِسْمَاعِيلَ بْنِ عُبَيْدِ اللَّهِ، عَنْ أَبِي صَالِحٍ الأَشْعَرِيِّ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ـ ﷺ ـ أَنَّهُ عَادَ مَرِيضًا وَمَعَهُ أَبُو هُرَيْرَةَ مِنْ وَعْكٍ كَانَ بِهِ فَقَالَ رَسُولُ اللَّهِ ـ ﷺ ـ " أَبْشِرْ فَإِنَّ اللَّهَ يَقُولُ هِيَ نَارِي أُسَلِّطُهَا عَلَى عَبْدِيَ الْمُؤْمِنِ فِي الدُّنْيَا لِتَكُونَ حَظَّهُ مِنَ النَّارِ فِي الآخِرَةِ " .
