When the Prophet ﷺ fell ill in his fatal illness, he started saying, "With the highest companion."  

البخاري:٤٤٣٦ – حَدَّثَنَا مُسْلِمٌ حَدَّثَنَا شُعْبَةُ عَنْ سَعْدٍ عَنْ عُرْوَةَ عَنْ عَائِشَةَ قَالَتْ

لَمَّا مَرِضَ النَّبِيُّ ﷺ الْمَرَضَ الَّذِي مَاتَ فِيهِ جَعَلَ يَقُولُ فِي الرَّفِيقِ الأَعْلَى
