Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: "Soon you will migrate to the land of Syria, and it will be conquered for you. There will be a disease there like a boil or like a huzzah (a pain felt in the heart or liver), which will seize the lower part of a man's belly (or the blood vessels). Through it Allah Almighty will grant the people martyrdom, and through it He will purify their deeds." (After that Sayyiduna Mu'adh (may Allah be pleased with him) supplicated:) "O Allah, if You know that Mu'adh bin Jabal (may Allah be pleased with him) heard this from the Messenger of Allah, then grant him (that is, Sayyiduna Mu'adh) and his household the most abundant share of it." The narrator says: The plague then overtook them, and not one of them was left. Its boil appeared on his index finger, and he used to say: "It would not please me to have red camels in exchange for it."
Ahmad recorded it. The narrator Isma'il bin Ubaydullah did not meet Sayyiduna Mu'adh (may Allah be pleased with him).
