Imam Bukhari : 5293

حَدَّثَنَا إِسْحَاقُ أَخْبَرَنَا حَبَّانُ حَدَّثَنَا دَاوُدُ بْنُ أَبِي الْفُرَاتِ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ بُرَيْدَةَ عَنْ يَحْيَى بْنِ يَعْمَرَ عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَأَنَّهَا أَخْبَرَتْنَا أَنَّهَا سَأَلَتْ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ الطَّاعُونِ فَأَخْبَرَهَا نَبِيُّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ كَانَ عَذَابًا يَبْعَثُهُ اللَّهُ عَلَى مَنْ يَشَاءُ فَجَعَلَهُ اللَّهُ رَحْمَةً لِلْمُؤْمِنِينَ فَلَيْسَ مِنْ عَبْدٍ يَقَعُ الطَّاعُونُ فَيَمْكُثُ فِي بَلَدِهِ صَابِرًا يَعْلَمُ أَنَّهُ لَنْ يُصِيبَهُ إِلَّا مَا كَتَبَ اللَّهُ لَهُ إِلَّا كَانَ لَهُ مِثْلُ أَجْرِ الشَّهِيدِتَابَعَهُ النَّضْرُ عَنْ دَاوُدَ

"Ishaq narrated to us, Habban narrated to us, Daud bin Abu Al Furat narrated to us, Abdullah bin Buraidah narrated from Yahya bin Ya'mar from Aisyah, the Prophet’s wife, peace be upon him, who said: She asked the Messenger of Allah, peace be upon him, about the plague. He informed her: It was a punishment sent by Allah on whom He willed, but Allah made it a mercy for believers. No servant in a plague-stricken land stays patiently, knowing nothing will afflict him except what Allah has decreed, but he will have the reward of a martyr. This was supported by An Nadlr’s narration from Daud.
