The Holy Quran 18:71 — Surah Al-Kahf
Arabic text
فَٱنطَلَقَا حَتَّىٰٓ إِذَا رَكِبَا فِى ٱلسَّفِينَةِ خَرَقَهَا ۖ قَالَ أَخَرَقْتَهَا لِتُغْرِقَ أَهْلَهَا لَقَدْ جِئْتَ شَيْـًٔا إِمْرًا
Translation
So they proceeded until (when they needed to cross a river) they boarded a boat (belonging to some poor people who offered to transport them free of charge) and (as they disembarked after crossing) he (Khidr) made a hole in it (by removing a few planks). (Surprised at this,) Moosa عليه الصلاة والسلام exclaimed, "Have you made a hole to drown the people of the boat? You have certainly perpetrated (done) a grave act."
Tafsir (excerpt) — Tafsir Usmani
