Asalamalakum brother.

I question is very sensitive and I am unable to get right answers. Please help me!!

Firstly, I want to know whether Allah is Noor? And is it right to call Noor as Light?
Secondly, Was Prophert Muhammad (Peace be Upon him) a Noor himself or a human being or both?
Thirdly, if ALLAH (s.w.t) is Noor, and Prophet Muhammad (Peace Be Upon him) and Angels are made up of Noor... does it not contradict with Surah- Ikhlas, and the Oneness of ALLAH, and ALLAH is One and he has no partners or children from Him?
And my final question, is it right to say that Prophet(s) are alive in their graves or to say they are alive?

Please give me your answers. And it would be very helpful if you give me references too, so that I can pass this important message to my other brothers too.

May ALLAH bless us. Ameen.

Allah Hafiz.
