Tafsir of Al-Kahf 18:84

The word: سَبَب (sabab) used in: وَآتَيْنَاهُ مِن كُلِّ شَيْءٍ سَبَبًا (and provided for him a way to everything - 84) is employed in the Arabic lexicon to denote everything harnessed to achieve an objective. It includes material instru¬ments and resources as well as knowledge, insight and experience etc. (al-Bahr al-Muhit). As for the expression: مِن كُلِّ شَيْءٍ (to everything), it means all things needed by a ruler to run the state system. The sense of the verse is that Allah Ta` ala had provided for the righteous king Dhul-Qar¬nain practically everything needed at that time in order that he could maintain his just rule, establish universal peace and extend his area of influence to other countries.
