"Islamic tradition says Muhammad ascended to heaven on a mule, that he healed the broken leg of a companion, that he fed large groups with little food, that he turned a tree branch into a steel sword, and that he was responsible for other supernatural accomplishments...'Correct me if I'm wrong, but as I read the Koran, essentially there aren't any miracles, apart from the supposed miracle of the Koran itself...[T]hese miracles are reported in Islamic tradition, which is where they really proliferate...

[T]he so-called Hadith...[H]ere's what's important:  this Islamic tradition comes hundreds of years after Muhammad's life and therefore isn't comparable to the gospels, which were written down within the first generations when the eyewitnesses were still alive...[I]t's simply not comparable le to these legendary stories about Muhammad that accumulated man, many years later in Islamic tradition...

...Perhaps in the sense that later the Hadith seemed to find it necessary to invent miracles for Muhammad.  he never claimed any such things for himself.  Basically, these stories illustrate how non-historical reports arise by legendary influences over centuries of time, in contrast to the gospels, where miracles reports are part of the earliest strata of sources.'
