"The Messenger of Allah ﷺ had dispatched Abu 'Ubaidah bin Al-Jarrah, so he arrived with the wealth from Al-Bahrain. When the Ansar had heard of the arrival of Abu 'Ubaidah they were attending Salat Al-Fajr. So the the Messenger of Allah ﷺ performed the Salat and when he finished, they assembled before him. The Messenger of Allah ﷺ smiled when he saw them, then he said: 'I think that you heard that Abu 'Ubaidah has arrived with something?' They said: 'Yes O Messenger of Allah! 'He said: 'Then receive good news, and hope for what will please you. By Allah! It is not poverty that I fear for you, but what I fear for you is that the world will be presented for you just as it was presented for those before you,then you will compete for it, just as they competed for it, and it will destroy you, just as it destroyed them.'
