﴿ قَالَ يَٰنُوحُ إِنَّهُۥ لَيْسَ مِنْ أَهْلِكَ ۖ إِنَّهُۥ عَمَلٌ غَيْرُ صَٰلِحٍۢ ۖ فَلَا تَسْـَٔلْنِ مَا لَيْسَ لَكَ بِهِۦ عِلْمٌ ۖ إِنِّىٓ أَعِظُكَ أَن تَكُونَ مِنَ ٱلْجَٰهِلِينَ ﴾
“[God] answered: "O Noah, behold, he was not of thy family, for, verily, he was unrighteous in his conduct. And thou shalt not ask of Me anything whereof thou canst not have any knowledge: thus, behold, do I admonish thee lest thou become one of those who are unaware [of what is right]."”
