My dear brother Ehtesham has listed a number of evidences for Islam on his website. I will just list them here and lightly respond to them. God-willing when he provides a detailed description of all these points I will respond to them also.
1.) The Quran says the Bible (Both the Old and New Testaments) is corrupt. Today Scholars of the Bible say the same exact thing-- Both the Old and New Testaments(especially the New Testament) have been badly edited, corrupted and distorted over time.
The first problem with this statement is the fact that the Qur'an does not imply that the Injeel is corrupted.
Secondly, the scholars who imply this are secular and humanists who apply certain methods to exclude the supernatural aspect of the Bible. These methods are philosophical in nature not historical; furthermore, these methodologies will equally debunk the Qur'an and hence the religion of Islam.
Thirdly, Christians who apply e.g. textual criticism or redaction criticism often apply the words critic, problem, corruption (I myself do that), however these words are not meant in a way to imply the nature or extent of corruption, which the Muslim is in need of to protect his own Qur'an from the reliability of the previous revelations.
2.) Scienctific Miracles from the Quran. Nobody has been able to refute many Scientific claims of the Quran. This is the biggest evidence that the Quran is not from a human
rather from Allah-- the God of All.
This claims seems very odd to me. I have done extensive studies on science also in relation to Islam and Greek philosophy. The fact is that most of the science described in the Qur'an is wrong. Furthermore, these claims were also common knowledge among the ancient intellectuals who preceeded Islam.
3). The Miracles of Prophet Muhammad (peace be upon him). Prophet Muhammad was able to perform miracles, something a false prophet can't do or an ordinary human
can do-- there was something supernatural in him where he was able to do miracles.
Firstly I disagree with the statement that a false prophet cannot perform miracles. Many hindu holy men, satanists and spiritists perform miracles.
Secondly, the Qur'an nowhere ascribes any miracles to Muhammad, quite the opposite it claims that the only miracle of Muhammad was revelation of the Qur'an, a book whose integrity has been refuted both historically, logically, scientifically and textually.
Thirdly, even though the Hadiths records miracles ascribed to Muhammad, Ethesham and other Muslims have to agree that based upon their own methodology these are human writings and ideas that were passed on from person to person for hundreds of years. If these traditions are to be considered reliable why does Ethesham distrust the succession, transmission and preservation of the Gospel material in the first century?
4.) True Prophcies of the Quran. More evidence its from the divine.
I am at loss as to what prophesies we are dealing with here.
5). True Prophcies of Prophet Muhammad-- more evidence he is a Prophet of God.
Again, I which which prophesies we are dealing with here.
6) Perservation of the Quran-- Allah said he would protect the Quran (Quran 15:9). This is another miracle of the Quran.
An assessment of the Islamic material shows that Muhammad was indeed dependent upon his followers in the writing or creation of the Qur'an; hence the Qur'an seems to be more of a fabrication. The number of Greek scientific ideas, Jewish fables, and Gnostic ideas simply confirms this.
Secondly, the Hadiths reveal that Muslims and even Muhammad in Muhammad's time were unable to preserve the Qur'an. When Muhammad died the situation of the Qur'an was chaotic and much of its content had been lost.
Thirdly, when the Qur'an was compiled after Muhammad's death, a civil war almost broke out since the variaty Qur'an versions were not matching.
Forthly, the Muslim rulers decided to favour only one Qur'anic version (the one of Zaid) an inferior version and burn the remaining ones. Those who had proved themselves to the most of reciters within Muhammad's time were literally forced to hand over their qur'ans to be burned.
Sounds to me like an organised and enforced corruption, of political nature. The fact is, there is no reason to trust a trustful transmission of the Qur'an before we see the varity of these Qur'an's that existed prior to Uthman's destruction and corruption of the Qur'an and we can compare these.
Fifthly, we know that even the manuscript of Hafsa, which Uthaman utilized for the corruption of the Qur'an was later destroyed to cover up errors.
7) Prophet Muhammad was foretold in the Old Testament. He may have also been foretold in the New Testament as well.
There not a single reference to Muhammad in the Bible, neither in the Old or New Testament.
The prophet in the Torah is Israelite and does not apply to Muhammad neither in nature or action.
The paraclete in John's Gospel does not apply either and neither can it since Muslims claim that John's Gospel is a complete corruption and fabrication and total embellishment of primitive Christianity.
Furthermore, from a Christian point of view, the only mention of Muhammad in the New Testament is categorized under the variaty of warnings of future false prophets, who do not meet the standard or doctrine of Jesus' or apostolic doctrine.
