Tafsir of Ar-Rahman 55:34

{ فبأي آلاء ربكما تكذبان }

(Meaning: which of the warnings, admonitions, concessions, and pardons—alongside complete power to punish—do you both deny?)

And it is said: Regarding the last interpretation mentioned previously, [it refers to] whatever logical ascents and traditional stairs the Glorified One has set up, by which you penetrate to what is beyond the exalted heavens.
