Narrated ASSAILANT:
I asked Sir about the Statement of Allah:
'And was at a distance of but two bow-lengths or (even) nearer. So did Allah convey the Inspiration to His slave (Gabriel) and then he (Gabriel) conveyed that to Muhammad.' (53.10) He said, "Abdullah (bin Mas'ud) informed us that Muhammad had seen Gabriel with six hundred wings."
