Taa-Haa 20:114

So Exalted is Allah, the True Sovereign[41]. Do not hasten to [recite] the Qur’an before its revelation to you is concluded[42], and say, “My Lord, increase me in knowledge.”

[41] Of everything in existence.
[42] Prophet Muhammad (ﷺ) was eager to recite the Qur’an while it was being revealed, so Allah Almighty told him to avoid being in haste in order to learn them before the verses are properly delivered; rather, listen to them attentively.

So high [above all] is Allāh, the Sovereign,[861] the Truth.[862] And, [O Muḥammad], do not hasten with [recitation of] the Qur’ān before its revelation is completed to you, and say, "My Lord, increase me in knowledge."

[861] And owner of everything in existence.
[862] Or "the True Reality," i.e., the real and permanent existence upon which all other existence depends.

114. Then High above all be Allâh, the True King. And be not in haste (O Muhammad صلى الله عليه وسلم) with the Qur’ân before its revelation is completed to you, and say: "My Lord! Increase me in knowledge."

Then exalted be Allah, the True King! And hasten not (O Muhammad) with the Qur'an ere its revelation hath been perfected unto thee, and say: My Lord! Increase me in knowledge.
