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.
