Al-Kahf • BN-TAFSEER-IBN-E-KASEER
﴿ فَٱنطَلَقَا حَتَّىٰٓ إِذَا رَكِبَا فِى ٱلسَّفِينَةِ خَرَقَهَا ۖ قَالَ أَخَرَقْتَهَا لِتُغْرِقَ أَهْلَهَا لَقَدْ جِئْتَ شَيْـًٔا إِمْرًۭا ﴾
“And so the two went on their way, till (they reached the seashore; and] when they disembarked from the boat [that had ferried them across], the sage made a hole in it-[whereupon Moses] exclaimed: "Hast thou made a hole in it in order to drown the people who may be [travelling] in it? Indeed, thou hast done a grievous thing!"”
