Qur'an 20:114

فَتَعَـٰلَى ٱللَّهُ ٱلْمَلِكُ ٱلْحَقُّ ۗ وَلَا تَعْجَلْ بِٱلْقُرْءَانِ مِن قَبْلِ أَن يُقْضَىٰٓ إِلَيْكَ وَحْيُهُۥ ۖ وَقُل رَّبِّ زِدْنِى عِلْمًا

“So high [above all] is Allāh, the Sovereign, the Truth. 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."”
