Well yes. Happens all the time.
However, in this instance, Islam defines its belief in God as the God of Abraham as found in the Bible. Islam's full understanding of God is skewed of course, but they worship the same God as the Jews and the Christians.
I automatically discount the opinions of people who put themselves in God's chair and decide for themselves the fate of another's soul. None of us can know how far God's mercy reaches.
Well, not really, although it certainly seems that way if you don't pay attention. The problem is that Islam didn't change their deity to match that of Abraham (Ibrahim), but instead re-wrote history to suggest that Abraham worshipped Allah instead of Yahweh. They say that Abraham built the Kaaba (a site that was historically, before Mohammed, always used to worship a pantheon, something that is incompatible with what we know of the biblical Abraham). In addition, nearly all the stories they tell describe details that are incompatible with the biblical story. If I tell the story of Noah but mention that Marduk told Noah to build the ark, that doesn't make Marduk another name for the True Deity.
Maybe it is the same god you worship but most professing Christians and jews think you are worshipping a flase god if you agree with them.
ALLAH - THE FICTITIOUS 'MOON GOD'
In Old Testament times, Nabonidus (555-539 BC), the last king of Babylon, built Tayma, Arabia as a center of Moon-god worship. Segall stated, "South Arabia's stellar religion has always been dominated by the Moon-god in various variations." When the popularity of the Moon-god waned elsewhere, the Arabs remained true to their conviction that the Moon-god was the greatest of all gods. While they worshipped 360 gods at the Kabah in Mecca, the Moon-god was the chief deity. Mecca was in fact built as a shrine for the Moon-god. The pagan Arabs worshipped the Moon-god Allah by praying toward Mecca several times a day; making a pilgrimage to Mecca; running around the temple of the Moon-god called the Kabah; kissing the black stone; killing an animal in sacrifice to the Moon-god; throwing stones at the devil; fasting for the month which begins and ends with the crescent moon; giving alms to the poor, etc.
The Muslim's claim that Allah is the God of the Bible and that Islam arose from the religion of the prophets and apostles is refuted by solid, overwhelming archeological evidence. Islam is nothing more than a revival of the ancient Moon-god cult. It has taken the symbols, the rites, the ceremonies, and even the name of its god from the ancient pagan religion of the Moon-god. As such, it is sheer idolatry and must be rejected by all those who follow the Torah and Gospel.

WHO RECEIVED GOD'S COVENANT?
As the foundation of the Islamic faith, Muslims are taught that Ishmael was their father, and that Ishmael received the Covenant of God through Abraham. In the Koran, Surah III reads: "We believe in God, and that which has been sent down on us, and sent down on Abraham and Ishmael, Isaac and Jacob, and the Tribes, and in that which was given to Moses and Jesus, and the prophets, of their Lord; we make no division between [distinction among] any of them, and to Him we surrender. "Surah III
