The Holy Quran 18:26 — Surah Al-Kahf

Arabic text

قُلِ ٱللَّهُ أَعْلَمُ بِمَا لَبِثُوا۟ ۖ لَهُۥ غَيْبُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۖ أَبْصِرْ بِهِۦ وَأَسْمِعْ ۚ مَا لَهُم مِّن دُونِهِۦ مِن وَلِىٍّ وَلَا يُشْرِكُ فِى حُكْمِهِۦٓ أَحَدًا

Translation

Say, "(Differing about the period will not benefit us) Allaah knows best how long they stayed (in the cave, so refer the matter to Him). He has knowledge of the unseen things within the heavens and the earth. How well does He see and hear! (There is nothing that He cannot see or hear.) They (those in the heavens and earth) have no helper besides Him, and none can be partner in His command (None shares power with Him)."

Tafsir (excerpt) — Tafsir Usmani

The knowledge and power of Allah: the historians stated in several ways the length of time they slept before waking. The most correct is what Allah tells; all the hidden secrets of the heavens and the earth are in His knowledge. Nothing is hidden from His sight. That is, just as His knowledge encompasses all, His power and authority also prevail over all.
