Mishkat al-Masabih 5 Funerals كتاب الجنائز 72

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ مَاتَ مَرِيضًا مَاتَ شَهِيدًا أَوْ وُقِيَ فِتْنَةَ الْقَبْرِ وَغُدِيَ وَرِيحَ عَلَيْهِ بِرِزْقِهِ مِنَ الْجَنَّةِ» . رَوَاهُ ابْنُ مَاجَهْ وَالْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ

Abu Huraira reported God’s messenger as saying, “He who dies of an illness dies as a martyr, or he will be guarded from the trial in the grave, and will have his provision brought him morning and evening from paradise.” Ibn Majah and BaihaqI, in Shu’ab al-iman , transmitted it.
