قَالَ رَبِّ إِنِّىٓ أَعُوذُ بِكَ أَنْ أَسْـَٔلَكَ مَا لَيْسَ لِى بِهِۦ عِلْمٌۭ ۖ وَإِلَّا تَغْفِرْ لِى وَتَرْحَمْنِىٓ أَكُن مِّنَ ٱلْخَٰسِرِينَ
He said: My Lord! Lo! in Thee do I seek refuge (from the sin) that I should ask of Thee that whereof I have no knowledge. Unless Thou forgive me and have mercy on me I shall be among the lost.
