Sahih Bukhari – Hadith No : 4906

Narrated Ash-Shaibani: I asked Zirr 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.”
