It is narrated from Sayyiduna Amr bin Aas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent me a message saying, "Put on your clothes and weapons and come to me." I came to the service of the Prophet (peace and blessings be upon him) while he was performing ablution. The Prophet (peace and blessings be upon him) looked up at me and then lowered his head. The Prophet (peace and blessings be upon him) said: "I intend to appoint you as the commander of an army. Allah will keep you safe and grant you spoils of war, or He will grant you a righteous desire for wealth." I said: "O Messenger of Allah! I did not become a Muslim out of greed for wealth and riches, but rather out of desire for Islam. I became a Muslim so that I could remain in the company of the Messenger of Allah (peace and blessings be upon him)." The Messenger of Allah (peace and blessings be upon him) said: "O Amr! Good wealth is a good thing for a righteous man."
