Tafsir of Al-Hijr 15:97

(And We already know that your breast is constrained by what they say) of words of polytheism and mockery. The sentence is embellished with emphasis to signify the certainty of the consolation it contains. The present tense form is used to signify the continuity of [Our] knowledge, corresponding to the continuity of that to which it relates, based on the continued persistence of the statements of the disbelievers that necessitate it.
