dream

Salam Alaykum, ShaikhI overheard some poeople in a park discussing the issue of seeing Allah ( subhanahu wa ta'ala ) in a dream to the extent one said that a person can get some zikr given in such a dream . I am not sure about this but need some clarification from you .may Allah continue to guarantee your health and eeman - ameen  

Dear Scholar's, As-salamu `alaikum! I have 3 questions. 1. I have a friend who says that he had dreamt of meeting our beloved prophet Muhammad(pbuh) but how can i believe him? 2. Who/how can a person dream of our beloved prophet? What must he/she attained before meeting him in his/her dreams? 3. What is Nur Muhammad? I'hv heard that it is the light that Allah first created before the angels, jinns, mankind and the whole universe. Is there any hadith about it? Jazakum Allahu khayran
