Sahih Muslim Book - 39, Hadith - 5787

وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، قَالَ : قَرَأْتُ عَلَى مَالِكٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عَبْدِ اللهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ ، أَنَّ عُمَرَ ، خَرَجَ إِلَى الشَّامِ فَلَمَّا جَاءَ سَرْغَ بَلَغَهُ أَنَّ الْوَبَاءَ قَدْ وَقَعَ بِالشَّامِ ، فَأَخْبَرَهُ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ ، أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ : إِذَا سَمِعْتُمْ بِهِ بِأَرْضٍ ، فَلاَ تَقْدَمُوا عَلَيْهِ ، وَإِذَا وَقَعَ بِأَرْضٍ وَأَنْتُمْ بِهَا ، فَلاَ تَخْرُجُوا فِرَارًا مِنْهُ فَرَجَعَ عُمَرُ بْنُ الْخَطَّابِ مِنْ سَرْغَ. وَعَنِ ابْنِ شِهَابٍ ، عَنْ سَالِمِ بْنِ عَبْدِ اللهِ ، أَنَّ عُمَرَ ، إِنَّمَا انْصَرَفَ بِالنَّاسِ مِنْ حَدِيثِ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ.

It was narrated from ‘Abdullah bin ‘Amir bin Rabi'ah that ‘Umar set out for Ash-Sham, but when he came to Sargh he heard that pestilence had broken out in Ash-Sham. ‘Abdur-Rahman bin ‘Awf told him that the Messenger of Allah (s.a.w) said: “If you hear of it breaking out in some land, do not go there, and if it breaks out in a land where you are, do not leave, fleeing from it.” So ‘Umar bin Al-Khattab returned from Sargh. It was narrated from Ibn Shihab from Salim bin ‘Abdullah that ‘Umar went back with the people.
