20:114
فَتَعَـٰلَى ٱللَّهُ ٱلْمَلِكُ ٱلْحَقُّ ۗ وَلَا تَعْجَلْ بِٱلْقُرْءَانِ مِن قَبْلِ أَن يُقْضَىٰٓ إِلَيْكَ وَحْيُهُۥ ۖ وَقُل رَّبِّ زِدْنِى عِلْمًا
fataʿālā l-lahu l-maliku l-ḥaqu walā taʿjal bil-qur'āni min qabli an yuq'ḍā ilayka waḥyuhu waqul rabbi zid'nī ʿil'man
exalted be God, the one who is truly in control. [Prophet], do not rush to recite before the revelation is fully complete but say, ‘Lord, increase me in knowledge!’
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."
