قَالَ رَبِّ إِنِّي أَعُوذُ بِكَ أَنْ أَسْأَلَكَ مَا لَيْسَ لِي بِهِ عِلْمٌ ۖ وَإِلَّا تَغْفِرْ لِي وَتَرْحَمْنِي أَكُن مِّنَ الْخَاسِرِينَ (47)
(11:47) Noah said: 'My Lord! I take refuge with You that I should ask you for that concerning which I have no knowledge. And if You do not forgive me and do not show mercy to me, I shall be among the losers. *51
*51). By relating the story of Noah's son, God has unequivocally and effectively made it clear that His justice is free from all biases, that His judgement is perfect and absolute. The Makkan unbelievers had entertained the illusion that God's wrath would not overtake them no matter how they behaved. They thought so because they happened to be the descendants of Abraham (peace be on him) and the devotees of a number of well-known gods and goddesses. In the past, Jews and Christians also entertained, as they still entertain, illusions of the same kind. In fact, there are also many deviant Muslims who place their reliance on false hopes. They believe that since they are descendants or devotees of some saints, the intercession of those saints will enable them to escape God's justice.
However, the Qur'an portrays how one of the great Prophets helplessly watches his own flesh and blood drown. In a state of severe emotional agitation, he piteously implores God to forgive his son. In response, God rebukes him. Thus, we see that even a person of a Prophet's ranking failed to salvage an iniquitous son.
