Narrated `Abdullah bin 'Amir:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، أَخْبَرَنَا مَالِكٌ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرٍ ، أَنَّ عُمَرَ، خَرَجَ إِلَى الشَّأْمِ، فَلَمَّا كَانَ بِسَرْغَ بَلَغَهُ أَنَّ الْوَبَاءَ قَدْ وَقَعَ بِالشَّأْمِ، فَأَخْبَرَهُ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا سَمِعْتُمْ بِهِ بِأَرْضٍ فَلاَ تَقْدَمُوا عَلَيْهِ وَإِذَا وَقَعَ بِأَرْضٍ وَأَنْتُمْ بِهَا فَلاَ تَخْرُجُوا فِرَارًا مِنْهُ ".
`Umar went to Sham and when he reached Sargh, he got the news that an epidemic (of plague) had broken out in Sham. `Abdur-Rahman bin `Auf told him that Allah's Messenger (ﷺ) said, "If you hear that it (plague) has broken out in a land, do not go to it; but if it breaks out in a land where you are present, do not go out escaping from it."
