[Machine] I heard the Prophet ﷺ before his death say three things: None of you should die except while having good thoughts about Allah. The wording of their hadiths is similar.  

سَمِعْتُ النَّبِيَّ ﷺ قَبْلَ مَوْتِهِ بِثَلَاثٍ يَقُولُ لَا يَمُوتَنَّ أَحَدٌ مِنْكُمْ إِلَّا وَهُوَ يُحْسِنُ الظَّنَّ بِاللهِ ﷻ لَفْظُ حَدِيثِهِمَا سَوَاءٌ  

I heard Messenger of Allah ﷺ say three days before his death: None of you should die but hoping only good from Allah, the Exalted and Glorious. (Using translation from Muslim 2877c)   

سَمِعْتُ رَسُولَ اللهِ ﷺ قَبْلَ مَوْتِهِ بِثَلَاثَةِ أَيَّامٍ يَقُولُ لَا يَمُوتَنَّ أَحَدُكُمْ إِلَّا وَهُوَ حَسَنُ الظَّنِّ بِاللهِ ﷻ
