The sickness of the Prophet (saws) and his death
وَقَوْلِ اللَّهِ تَعَالَى: {إِنَّكَ مَيِّتٌ وَإِنَّهُمْ مَيِّتُونَ ثُمَّ إِنَّكُمْ يَوْمَ الْقِيَامَةِ عِنْدَ رَبِّكُمْ تَخْتَصِمُونَ}.
Sahih Bukhari
حَدَّثَنَا مُسْلِمٌ، حَدَّثَنَا شُعْبَةُ، عَنْ سَعْدٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ لَمَّا مَرِضَ النَّبِيُّ صلى الله عليه وسلم الْمَرَضَ الَّذِي مَاتَ فِيهِ جَعَلَ يَقُولُ " فِي الرَّفِيقِ الأَعْلَى ".
Narrated `Aisha: When the Prophet (ﷺ) fell ill in his fatal illness, he started saying, "With the highest companion."
