* If fi yawm is co-related to waqi’, it implies ‘50,000 year long Day of Judgement when the torment will befall’. But if it is co-related to ta‘ruju, it denotes fifty millennium year a day speed of ascension by the angels and by the souls of the believers that ascend towards Allah’s Throne. It is known to Allah alone as to what time they take to reach the destination. This generates the concept of ‘light year’.
