Surat Hud (45-46)

{وَنَادَى نُوحٌ رَّبَّهُ فَقَالَ رَبِّ إِنَّ ابُنِي مِنْ أَهْلِي وَإِنَّ وَعْدَكَ الْحَقُّ وَأَنتَ أَحْكَمُ الْحَاكِمِينَ} (هود: 45)

45- Noah invoked his Lord saying: O my Lord, my son who has drowned was one of my family, and You promised to rescue my family. Your Promise is truthful and You never break it; You are the Most Knowledgeable and the Most Just.

{قَالَ يَا نُوحُ إِنَّهُ لَيْسَ مِنْ أَهْلِكَ إِنَّهُ عَمَلٌ غَيْرُ صَالِحٍ فَلاَ تَسْأَلْنِ مَا لَيْسَ لَكَ بِهِ عِلْمٌ إِنِّي أَعِظُكَ أَن تَكُونَ مِنَ الْجَاهِلِينَ} (هود: 46)

46- Allah (Glory be to Him) said which means: O Noah, your son was not from your family which I had promised to rescue. There is no true kinship between a believer and a disbeliever even if they are relatives. Creed is the basis, so he is not one of your family as long as he is a disbeliever. Disbelief is a corrupt creed and bad deed, so do not ask from me something you do not know whether it is correct or not. I advise you to leave the matter to me lest you would be from the ignorant.
