It is narrated from Hazrat Mu'adh (may Allah be pleased with him) that I heard the Noble Prophet (peace and blessings be upon him) say: Soon you will migrate towards Syria and it will be conquered at your hands, but there a disease of boils and blisters will be imposed upon you, which will seize a person by the leg of the ladder. Allah will grant them martyrdom through it and purify their deeds. O Allah! If You know that Mu'adh bin Jabal heard this hadith from the Noble Prophet (peace and blessings be upon him), then grant him and his family an ample share of it. Consequently, all of them were afflicted with the plague and not a single one of them remained alive. When the plague swelling appeared on the finger of martyrdom of Hazrat Mu'adh (may Allah be pleased with him), he would look at it and say: I would not prefer to have a red camel in exchange for this.
