A non-Muslim researcher is asking about the proof that Jibreel spoke to the Prophet (peace and blessings of Allaah be upon him): Praise be to Allah. Jibreel (peace be upon him) spoke to Muhammad (peace and blessings of Allaah be upon him) directly, with no barrier in between, and the Prophet Muhammad (peace and blessings of Allaah be upon him) saw him in his true form. This was reported in many aayaat (verses of the Qur’aan) and ahaadeeth (reports of the things that the Prophet Muhammad (peace and blessings of Allaah be upon him) said and did). 1.Allaah says (interpretation of the meaning): “By the star when it goes down (or vanishes). Your companion (Muhammad) has neither gone astray nor has erred. Nor does he speak of (his own) desire. It is only a Revelation revealed. He has been taught (this Qur’aan) by one mighty in power [Jibreel (Gabriel)].” [al-Najm 53:1-5]
