Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah the Most High: "So (Allah) revealed to His slave [Muḥammad pbuh through Jibrīl (Gabriel a.s.)] whatever He revealed." (V.53:10)
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."
