Sayyiduna Amr bin Awf (may Allah be pleased with him), who was an ally of Banu Amir bin Lu'ayy and a Companion who fought at Badr, says that the Messenger of Allah (peace and blessings be upon him) sent Sayyiduna Abu Ubaydah bin al-Jarrah (may Allah be pleased with him) to collect the jizyah from the Magians of Bahrain. The governor of Bahrain was Sayyiduna al-Ala' bin al-Hadrami (may Allah be pleased with him), whom the Prophet (peace and blessings be upon him) had appointed after making peace. When Sayyiduna Abu Ubaydah (may Allah be pleased with him) came with wealth from Bahrain and the Ansar heard of his arrival, they completed the morning prayer with him (peace and blessings be upon him) and then presented themselves before him. He (peace and blessings be upon him) smiled on seeing them and said: "You must have heard that Abu Ubaydah has brought wealth?" They said: O Messenger of Allah (peace and blessings be upon him), you have spoken truly. He (peace and blessings be upon him) said: "Receive glad tidings of what will please you. I do not fear poverty for you, but I fear for you the prosperity of the world, just as the world was spread out for those before you and they vied with one another for it, and it distracted them; lest it distract you too."
