An eyewitness to the incident of the plague of Amwas narrates that when the suffering of Sayyiduna Abu Ubaidah bin Al-Jarrah (may Allah be pleased with him) intensified, he stood before the people to deliver a sermon and said: O people! This affliction is the mercy of your Lord, the call of your Prophet, and the death that befell the righteous before you, and Abu Ubaidah prays to Allah to grant him his share from it. Thus, he was martyred in this very plague. May Allah have mercy on him. After him, Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) took over his position and, delivering a sermon, said: O people! This affliction is the mercy of your Lord, the call of your Prophet, and the death that befell the righteous before you, and Mu'adh prays to Allah to grant the family of Mu'adh their share from it. Consequently, his son Abdur Rahman contracted this disease and was martyred. Then Sayyiduna Mu'adh (may Allah be pleased with him) stood up again and prayed for himself, so a plague sore appeared on his palm. I have seen him looking at this plague sore, kissing his palm, and saying repeatedly: Even if I were given the whole world in exchange for this, I would not be pleased. In any case, he too was martyred. After him, Sayyiduna Amr bin Al-As (may Allah be pleased with him) was appointed as their deputy. He stood and delivered a sermon, saying: O people! When this affliction comes, it starts to blaze like fire, so protect yourselves from it by going to the mountains. Upon hearing this, Abu Wathilah Hudhali said: Despite being a companion of the Prophet (peace be upon him), you are not saying the right thing. By Allah! You are worse than my donkey. He replied: I will not answer you, but by Allah! We will not remain in this state. Thus, he left that area, and the people also dispersed and left, and in this way, Allah removed this disease from them. Someone who witnessed Sayyiduna Amr's (may Allah be pleased with him) decision informed Sayyiduna Umar (may Allah be pleased with him) about it, and he did not express any displeasure over it.
