"Is Allah not the wisest of the judges?"

That is: Is He who has done what has been mentioned not the wisest of judges in craftsmanship and governance, such that the lack of resurrection and recompense might be imagined? Since it is impossible that He, Glory be to Him, is not the wisest of judges, resurrection and recompense are therefore established. The sentence serves as an affirmation of what preceded it.

It has been said that "the Judge" (al-Hakim) here is in the sense of "the One who decrees" (al-Qadi), and thus it is a threat to the disbelievers, meaning that He, Almighty and Majestic is He, will judge against them with the punishment they deserve. In any case, the interrogation—according to what has been said—is an affirmation following a negation.

Evidence for this is what was recorded by al-Tirmidhi, Abu Dawud, and Ibn Marduyah from Abu Hurayrah, who said: The Messenger of Allah (may Allah’s peace and blessings be upon him) said: "Whoever among you reads 'By the Fig and the Olive' and reaches His saying, the Almighty, 'Is Allah not the wisest of the judges?', let him say: 'Yes, and I am among those who testify to that.'"

It has also been reported in some narrations that when the Prophet (may Allah’s peace and blessings be upon him) reached this verse, he would say: "Glory be to You, yes indeed." Whatever pertains to this has already been discussed in the interpretation of Surah La Uqsimu bi-Yawm al-Qiyamah (The Resurrection), so recall it.
