Our master Amr ibn Awf (Allah be pleased with him) reported:

The Messenger of Allah, (peace and blessings of Allah be upon him) said,

“By Allah, it is not poverty I fear for you, but rather I fear you will be given the wealth of the world just as it was given to those before you. You will compete for it just as they competed for it and it will destroy you just as it destroyed them.”
