Muslim transmitted it.
In Tirmidhi's version he said Muhammad saw his Lord. `Ikrima said he asked whether God does not say, "The eyes do not perceive Him but He perceives the eyes[*]," and he replied, "Out upon you! That is when He shines forth with His own essential light; but he has seen his Lord twice."
