it is not given to any human being that allah should speak to him unless by inspiration or from behind a veil or he sends a messenger to reveal what he wills by his leave. verily he is most high most wise.
وما كان لبشر أن يكلمه الله إلا وحيا أو من وراء حجاب أو يرسل رسولا فيوحي بإذنه ما يشاء إنه علي حكيم
