Did the Prophet [pbuf&hf] have complete knowledge of the Qur'an since birth [or even before]? What is the clear Quranic evidence for this?
If the answer is yes, how do you explain the fact that Gibrael used to come to him with revelation? What is the need for Gibrael to come when the Prophet already has the knowledge?
How do you explain Surah Furqaan, verse 32 where Allah seemingly talks about gradual revelation to the Prophet in order to strengthen his heart?
