فَأَوْحَيْنَآ إِلَيْهِ أَنِ ٱصْنَعِ ٱلْفُلْكَ بِأَعْيُنِنَا وَوَحْيِنَا فَإِذَا جَآءَ أَمْرُنَا وَفَارَ ٱلتَّنُّورُ ۙ فَٱسْلُكْ فِيهَا مِن كُلٍّۢ زَوْجَيْنِ ٱثْنَيْنِ وَأَهْلَكَ إِلَّا مَن سَبَقَ عَلَيْهِ ٱلْقَوْلُ مِنْهُمْ ۖ وَلَا تُخَٰطِبْنِى فِى ٱلَّذِينَ ظَلَمُوٓا۟ ۖ إِنَّهُم مُّغْرَقُونَ
Then We inspired in him, saying: Make the ship under Our eyes and Our inspiration. Then, when Our command cometh and the oven gusheth water, introduce therein of every (kind) two spouses, and thy household save him thereof against whom the Word hath already gone forth. And plead not with Me on behalf of those who have done wrong. Lo! they will be drowned.
Surah Al-Muminoon(23:27)
