Ishmael: Eldest son of Abraham by his concubine Hagar; born when Abraham was eighty-six years of age (Gen. xvi. 15, 16). God promised Abraham that His blessing should be upon Ishmael, who, He foretold, would beget twelve princes and would become a great nation (Gen. xvii. 18, 20).
Islam can be seen as God keeping His promise.
The Arabs weren't always Muslim and there are lots of Muslims today that are not Arabs.
Theophilos I'm gonna expand on your post...
This "Beast from the Earth" is said to:
Revelation 13:13 And he will do great signs, such as, he will make fire to come down from heaven on the earth before men.
Muslims consider the verses in the Quran "signs from heaven", the Arabic word "surah" means a "sign" or "revelation":
We will soon show them OUR signs
in the Universe and in their own souls, until it will become quite clear to them that it is the truth. Is it not sufficient as regards your Lord that HE is a witness over all things? (41:53)
As for "fire from heaven" did you notice how many hellfire verses are in the Quran? Here are a few of my favourites:
Our Lord, Thou wilt certainly assemble mankind together on the Day about which there is no doubt; surely, ALLAH never fails in HIS promise. (As for) those who disbelieve, surely neither their wealth nor their children shall avail them in the least against Allah, and these it is who are the fuel of the fire. (3:9-10)
And fear the Fire which has been prepared for the disbelievers. (3:131)
And WE shall cast terror into the hearts of those who disbelieved because they associate partners with ALLAH, for which HE has sent down no authority. Their abode is the Fire; and evil is the habitation of the wrongdoers. (3:151)
And surely, ALLAH has heard the utterance of those who said, "ALLAH is poor and we are rich." WE shall record what they have said, and their attempts to slay the Prophets unjustly; and WE shall say, "Taste ye the punishment of the burning;" (3:181)
And whoso disobeys ALLAH and HIS Messenger and transgresses HIS limits. HE will make him enter into the Fire; therein he shall abide; and he shall have an humiliating punishment. (4:14)
Those who disbelieve in Our Signs, We shall soon cause them to enter Fire. As often as their skins are burnt up, WE shall give them in exchange other skins that they may continue to taste the punishment. Surely, ALLAH is Mighty and Wise. (4:56)
That is your punishment, taste it then; and remember that for disbelievers there is the punishment of the Fire. (8:14)
(The stern command will say): "Seize ye him, and bind ye him, "And burn ye him in the Blazing Fire. "Further, make him march in a chain, whereof the length is seventy cubits! "This was he that would not believe in God Most High. (69:30-33)
