Translation:

23. "No intercession can avail in His Presence except for those for whom He has granted permission. So far (is this the case) that when terror is removed from their hearts (at the Day of Judgement then) will they say `What is it that your Lord commanded?' They will say `That which is true and just; and He is the Most High Most Great.' "

Notes (Tafseer)

3824. Cf. xx. 109, n. 2634, where I have explained the two possible modes of interpretation. Each soul is individually and personally responsible. And if there is any intercession, it can only be by Allah's gracious permission. For the Day of judgment will be a terrible Day, or Day of Wrath (Dies Irae) according to the Latin hymn, when the purest souls will be stupefied at the manifestation of Allah's Power. See next note.

3825. "Their hearts": the pronoun "their" is referred to the angels nearest to Allah. On the Day of Judgment there will be such an irresistible manifestation of Power that even they will be silent for a while, and will scarcely realise what is happening. They will question each other, and only thus will they regain their bearings. Or "their" may refer to those who seek intercession.

3826. In their mutual questionings they will realise that Allah's Judgment, as always, is right and just.
