Quran 11:46 — Hud (Hud)

قالَ يٰنوحُ إِنَّهُ لَيسَ مِن أَهلِكَ ۖ إِنَّهُ عَمَلٌ غَيرُ صٰلِحٍ ۖ فَلا تَسـَٔلنِ ما لَيسَ لَكَ بِهِ عِلمٌ ۖ إِنّى أَعِظُكَ أَن تَكونَ مِنَ الجٰهِلينَ

He said, "O Noah, he is not of your family. It is unrighteous to ask Me for something you do not know.* I enlighten you, lest you be like the ignorant."

[11:45] Noah implored his Lord: "My Lord, my son is a member of my family, and Your promise is the truth. You are the wisest of the wise."

[11:47] He said, "My Lord, I seek refuge in You, lest I implore You again for something I do not know. Unless You forgive me, and have mercy on me, I will be with the losers."
