Hadith 4:81
Jabir said he heard God’s messenger say three days before his death, “See that none of you dies without having good expectations from God.” Muslim transmitted it.
وَعَنْ جَابِرٍ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَبْلَ مَوْتِهِ بِثَلَاثَةِ أَيَّامٍ يَقُولُ: «لَا يَمُوتَنَّ أَحَدُكُمْ إِلَّا وَهُوَ يُحْسِنُ الظَّنَّ بِاللَّه» . رَوَاهُ مُسلم
