Messenger of Allah ﷺ said, "Plague was a means of torture sent on a group of Israelis (or on some people before you). So if you hear of its spread in a land, don't approach it, and if a plague should appear in a land where you are present, then don't leave that land in order to run away from it (i.e. plague).  

سَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ فِي الطَّاعُونِ فَقَالَ أُسَامَةُ قَالَ رَسُولُ اللَّهِ ﷺ الطَّاعُونُ رِجْسٌ أُرْسِلَ عَلَى طَائِفَةٍ مِنْ بَنِي إِسْرَائِيلَ أَوْ عَلَى مَنْ كَانَ قَبْلَكُمْ فَإِذَا سَمِعْتُمْ بِهِ بِأَرْضٍ فَلاَ تَقْدَمُوا عَلَيْهِ وَإِذَا وَقَعَ بِأَرْضٍ وَأَنْتُمْ بِهَا فَلاَ تَخْرُجُوا فِرَارًا مِنْهُ قَالَ أَبُو النَّضْرِ لاَ يُخْرِجُكُمْ إِلاَّ فِرَارًا مِنْهُ  

What have you heard from Messenger of Allah ﷺ about plague? Thereupon Usama said: Messenger of Allah ﷺ said: Plague is a calamity which was sent to Bani Isra'il or upon those who were before you. So when you hear that it has broken out in a land, don't go to it, and when it has broken out in the land where you are, don't run out of it. In the narration transmitted on the authority of Abu Nadr there is a slight variation of wording.  

سَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ فِي الطَّاعُونِ فَقَالَ أُسَامَةُ قَالَ رَسُولُ اللَّهِ ﷺ الطَّاعُونُ رِجْزٌ أَوْ عَذَابٌ أُرْسِلَ عَلَى بَنِي إِسْرَائِيلَ أَوْ عَلَى مَنْ كَانَ قَبْلَكُمْ فَإِذَا سَمِعْتُمْ بِهِ بِأَرْضٍ فَلاَ تَقْدَمُوا عَلَيْهِ وَإِذَا وَقَعَ بِأَرْضٍ وَأَنْتُمْ بِهَا فَلاَ تَخْرُجُوا فِرَارًا مِنْهُ وَقَالَ أَبُو النَّضْرِ لاَ يُخْرِجُكُمْ إِلاَّ فِرَارٌ مِنْهُ  

Yahya related to me from Malik from Muhammad ibn al-Munkadir and from Salim ibn Abi'n-Nadr, the mawla of Umar ibn Ubaydullah that Amir ibn Sad ibn Abi Waqqas heard his father ask Usama ibn Zayd, "Have you heard anything from the Messenger of Allah ﷺ about the plague?" Usama said, "The Messenger of Allah ﷺ said, 'The plague is a punishment that was sent down on a party of the Banu Israil or whoever was before them. When you hear of it in a land, do not enter it. If it comes upon a land and you are in it, do not depart in flight from it.' " Malik said that Abu'n-Nadr said, "That is, do not depart with no other intention but flight."  

أَنَّهُ سَمِعَهُ يَسْأَلُ أُسَامَةَ بْنَ زَيْدٍ مَا سَمِعْتَ مِنْ رَسُولِ اللَّهِ ﷺ فِي الطَّاعُونِ فَقَالَ أُسَامَةُ قَالَ رَسُولُ اللَّهِ ﷺ الطَّاعُونُ رِجْزٌ أُرْسِلَ عَلَى طَائِفَةٍ مِنْ بَنِي إِسْرَائِيلَ أَوْ عَلَى مَنْ كَانَ قَبْلَكُمْ فَإِذَا سَمِعْتُمْ بِهِ بِأَرْضٍ فَلاَ تَدْخُلُوا عَلَيْهِ وَإِذَا وَقَعَ بِأَرْضٍ وَأَنْتُمْ بِهَا فَلاَ تَخْرُجُوا فِرَارًا مِنْهُ قَالَ مَالِكٌ قَالَ أَبُو النَّضْرِ لاَ يُخْرِجُكُمْ إِلاَّ فِرَارٌ مِنْهُ
