Muwatta Malik, Book 45, Hadith 1623 (In-Book) ⓘ

Yahya related to me from Malik from Ibn Shihab from Abdullah ibn Amir ibn Rabia that Umar ibn al-Khattab went out to ash-Sham. When he came to Sargh, near Tabuk, he heard that the plague had broken out in ash-Sham. Abd ar-Rahman ibn Awf told him that the Messenger of Allah, may Allah bless him and grant him peace, said, "If you hear that a land has a plague in it, do not go forward to it. If it comes upon a land which you are in, do not depart in flight from it." Umar ibn al- Khattab came back from Sargh.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرِ بْنِ رَبِيعَةَ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، خَرَجَ إِلَى الشَّامِ فَلَمَّا جَاءَ سَرْغَ بَلَغَهُ أَنَّ الْوَبَأَ قَدْ وَقَعَ بِالشَّامِ 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 ‏" ‏ ‏.‏ فَرَجَعَ عُمَرُ بْنُ الْخَطَّابِ مِنْ سَرْغَ ‏.‏
