The most surprising ‘revelation’ in the Quran is the fact that it does not contain a single report of any MIRACLE PERFORMED by Muhammad. 

       On the contrary, in several verses – more than twenty of them - they DENY him the ability to perform any, as an example to prove either the existence of Allah or to impress the pagans so that they may convert. 

17: 90 They say: "We shall not believe in thee until thou cause spring to gush forth for us from the earth 

       91        "Or (until) thou have a garden of date trees and vines and cause rivers to gush forth in their midst carrying abundant water;

      92        "Or thou cause the sky to fall in pieces as thou sayest (will happen) against us; or thou bring Allah and the angels before (us) face to face;

      93        "Or thou have a house adorned with gold or thou mount a ladder right into the skies.  No we shall not even believe in thy mounting until thou send down to us a book that we could read." Say: "Glory to my Lord! am I aught but a man an apostle?"  

     94        What kept men back from Belief when Guidance came to them was nothing but this: they said "Has Allah sent a man like us to be (His) Apostle?" 

         All the stories of ‘miracles’ attributed to Muhammad, are FALSE and INVENTED  reports, concocted years later by his followers in the Ahadith.

       The demand by the Qurayshites for miraculous proofs is understandable both from the cultural and psychological points of view. They could not accept that a mere human being, a less than equal to their nobility, could claim such superiority as Muhammad did. 

       They needed tangible and clear proofs that Allah was on his side as he claimed. 

13:7  “ And the unbelievers say: Why is not a sign sent down to him from his Lord? But thou art truly a warner, and to every people a guide” 

       This verse explains very clearly the function of Muhammad: he was only a warner and definitely not a miracle worker.

       *** It is important to point out that every single alleged 'miracle' in the Ahadith that Muhammad was a party to, was never witnessed by anyone else but Muhammad; invariably in darkness or at night. 

       All his encounters with the angel Gabriel were also not witnessed by a second party. 

       All of Muhammad's alleged 'miracles' are in contradistinction to the fact that the miracles of Moses were conducted in the full view of the Israelites and  the Egyptians and in broad daylight. 

       Another incredible difference is the fact that the miracles of Moses were forewarned while those of Muhammad were afterthoughts.

        For example, before any miracles befell Egypt, Pharaoh was warned of exactly what was going to happen to his country if he refused God’s commands. 

       In the case of Muhammad on the other hand,no such forewarnings were  ever mentioned. 

       Moreover, whereas in the Bible, the Almighty never ABROGATED a verse or CHANGED ‘His Mind’, whereas in the Quran there are at least 71 Surahs with a plethora of abrogated and abrogating verses asserting that the Omniscient Allah repeatedly changed ‘his mind’, invariably to ‘lessen a burden on the followers of Muhammad’ or to satisfy any of Muhammad’s personal needs.

       Of course such an ascription to Allah constitutes BLASPHEMY since it renders and reduces Allah - if Allah is the God of Israel & Jesus - to a mere fallible and ignorant mortal ***
