Most of these narratives are reported only by Hisham ibn `urwah reporting on the authority of his father. An event as well known as the one being reported, should logically have been reported by more people than just one, two or three.
LOL! Have they ever tried applying that logic to the existence Gibril or the Building of Mecca or Jesus...
I think that the narratives reporting this event are not only highly unreliable but also that on the basis of other historical data, the event reported, is quite an unlikely happening.
F**KING LOL, AGAIN!
It never ceases to amaze me how quickly the standards differ as soon as the Quran is placed in a bad light..
