COMMENTARY on 40:46
A. Yusuf Ali:

Translation:
In front of the Fire will they be brought, morning and evening: 4419 And (the sentence will be) on the Day that Judgment will be established: "Cast you the People of Pharaoh into the severest Penalty!"
Commentary:

4419  When the Judgement really comes, it is not like an ordinary physical disaster. The Fire of Punishment is ever present-morning and evening-i.e., at all times. The sentence becomes final and there is no mitigation.

 

Muhammad Asad:

Translation:
the fire [of the hereafter - that fire] which they had been made to contemplate [in vain], morning and evening: 31 for on the Day when the Last Hour dawns [God will say], “Make Phar­aoh’s folk enter upon suffering most severe!”
Commentary:
31  I.e., of which they had been warned, day-in and day-out, by prophets and believers like the one spoken of in this passage.
