However, 'Amir refrained from expressing any inclination towards Islam and said to the Prophet repeatedly, "I want to talk to you in seclusion". Every time he uttered this sentence he looked towards Arbad. However, although he looked at his face very intently he found him calm and tranquil. The Prophet said to him in reply: "Unless you embrace Islam this thing is not possible, (i.e. to see you alone)". At last 'Amir lost all hope of Arbad's assistance in the success of their plot.

The supplication of the Prophet was accepted soon. 'Amir had an attack of plague while he was on his way, and died in a very bad condition in the house of a woman belonging to the tribe of Bani Salul. As regards Arbad, he was struck by lightning in the desert and was burnt to death.

While giving him detailed instructions the Prophet also said to Mu'az: "Avoid harsh treatment with the people, and inform them of Divine blessings which are meant for the true believers.
