Master of the Day of Judgement: that is, [the day of] requite, the Day of Resurrection. The reason for the specific mention [of the Day of Judgement] is that the mastery of none shall appear on that Day except that of God, may He be exalted, as is indicated by [God’s words] ‘Whose is the Kingdom today?’ ‘God’s’ [Q. 40:16] (if one reads it mālik [as opposed to malik], then this signifies that He has possession of the entire affair on the Day of Resurrection, or else that He is ever described by this [expression], in the same way as [He is described as] ‘Forgiver of sin’ (ghāfir al-dhanb). Thus, one can validly take it as an adjective of a definite noun).
