Jalāl al-Dīn al-Maḥallī
تفسير : 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).
