Challenge for Muslims

I asked a question only, the Quran says produce a Surah like it, how does it make sense that I must produce a Surah like it yet it has to be part of the Quran...? This makes no sense at all. The Quran merely states produce a Surah like it however it is you Muslims now who are changing the words of the Quran to make the argument disappear. The Quran states no rules and regulations (like I see you doing) when it says produce a Surah like it. If someone fabricated it then the challenge of the Quran has been beaten. Early Muslim scholars of the 7th and 8th century did not deny this as fabricated either.

The biggest issue I have with Muhammad being a messenger is that all previous prophets had been spoken to by God. In his case the messages did not come directly from God but something claiming to be an angel.

Dr. Aslam wrote: Muslims believe that God does not communicate with human beings face to face. He sends his message through the arch angel. It is a belief the say way as you believe that God speaks to prophets directly. Whose belief is right and whose is wrong? The Quran says that rather than disputing these issues and having hatred of each other on them, let us come to a point of agreement about the oneness of God and the divine guidance as well as the day of judgment.

A bit confused here. I was told the Miraj was a conversation between God and Muhammad. Would you please elaborate?

Never did We send a Messenger or a Prophet before you, but; when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise:
(Quran 22 52, Mushin Khan)

And We did not send before you any messenger rasūl — this is a prophet who has been commanded to deliver a Message — or prophet nabī — one who has not been commanded to deliver anything — but that when he recited the scripture Satan cast into his recitation what is not from the Qur’ān but which those to whom he the prophet had been sent would find pleasing. The Prophet s had during an assembly of the men of Quraysh after reciting the following verses from sūrat al-Najm Have you considered Lāt and ‘Uzzā? And Manāt the third one? 5319-20 added as a result of Satan casting them onto his tongue without his the Prophet’s being aware of it the following words ‘those are the high-flying cranes al-gharānīq al-‘ulā and indeed their intercession is to be hoped for’ and so they the men of Quraysh were thereby delighted. Gabriel however later informed him the Prophet of this that Satan had cast onto his tongue and he was grieved by it; but was subsequently comforted with this following verse that he might be reassured of God’s pleasure thereat God abrogates nullifies whatever Satan had cast then God confirms His revelations. And God is Knower of Satan’s casting of that which has been mentioned Wise in His enabling him Satan to do such things for He does whatever He will.
