Abu Nadhrah says: "We were sitting in the company of Jabir bin Abdullah (R.A.) when he said: 'Soon the people of IRAQ will neither receive any food (grain) nor any money.'" We asked, "Why would such a thing happen?" He replied, "Because of the non-Arabs." (i.e they will prevent food from going into Iraq, in the form of "sanctions" to this day.) He then said: "Soon the people of Shaam (SYRIA) will neither receive any money nor grain." We asked as to why this would happen. He replied: "Because of the Romans (christians)."
The first sanctions where by the non Arabs which is a term very wide in meaning [United nations which is global fits this defanition and what occured] while the second sanctions is by the Romans or Europeans [up until the end of the Ottoman empire muslims used to call europeans people of ruum or romans since traditionally that was the power base untill its collapse] and we see today the E.U is increasingly gaining power, ability and will to do this espetially as the euro is replacing the American currency as the world currency.
Abu Hurairah related that the Messenger of Allah said, "Iraq will be prevented from its dirham (a currency) and its measurement; Sham will be prevented from its dinar (a currency) and its measurement; and Egypt will be prevented from its dinar and its measurement' . You will have returned from whence you began; you will return from whence you began; you will return from whence you began." Abu Hurairah said, "The flesh and blood of Abu Hurairah bore witness to that." (Muslim)
One aspect of the sanctions was the de-evaluation of the Iraqi currency where people lost trillions in one day in this manner they where prevented from there wealth, but this is just my understanding.
