Sayyiduna al-Miswar bin Makhramah (may Allah be pleased with him) narrates: The Ansar heard that Sayyiduna Abu Ubaydah (may Allah be pleased with him) had come with wealth from Bahrain. The Prophet (peace and blessings be upon him) had sent him to Bahrain. So they joined the Prophet (peace and blessings be upon him) in the morning (Fajr) prayer. When the Prophet (peace and blessings be upon him) finished the prayer, they presented themselves before him. When the Prophet (peace and blessings be upon him) saw them, he smiled and said: Perhaps you have heard that Abu Ubaydah has come, and has come with wealth? They said: Yes, O Messenger of Allah! The Prophet (peace and blessings be upon him) said: Receive glad tidings and hope for good. By Allah, it is not poverty that I fear for you; rather, the world will be poured out upon you, and you will vie for it just as those before you vied for it.
Ahmad recorded it, and its narrators are the narrators of the Sahih.
