وَلَا تَقُولَنَّ لِشَيْءٍ إِنِّي فَاعِلٌ ذَٰلِكَ غَدًا ٢٣
Nor say of anything, "I shall be sure to do so and so tomorrow"-
18:24
إِلَّا أَنْ يَشَاءَ اللَّهُ ۚ وَاذْكُرْ رَبَّكَ إِذَا نَسِيتَ وَقُلْ عَسَىٰ أَنْ يَهْدِيَنِ رَبِّي لِأَقْرَبَ مِنْ هَٰذَا رَشَدًا ٢٤
Without adding, "So please Allah!" and call thy Lord to mind when thou forgettest, and say, "I hope that my Lord will guide me ever closer (even) than this to the right road."
18:25
وَلَبِثُوا فِي كَهْفِهِمْ ثَلَاثَ مِائَةٍ سِنِينَ وَازْدَادُوا تِسْعًا ٢٥
So they stayed in their Cave three hundred years, and (some) add nine (more)
18:26
قُلِ اللَّهُ أَعْلَمُ بِمَا لَبِثُوا ۖ لَهُ غَيْبُ السَّمَاوَاتِ وَالْأَرْضِ ۖ أَبْصِرْ بِهِ وَأَسْمِعْ ۚ مَا لَهُمْ مِنْ دُونِهِ مِنْ وَلِيٍّ وَلَا يُشْرِكُ فِي حُكْمِهِ أَحَدًا ٢٦
Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever.
18:27
وَاتْلُ مَا أُوحِيَ إِلَيْكَ مِنْ كِتَابِ رَبِّكَ ۖ لَا مُبَدِّلَ لِكَلِمَاتِهِ وَلَنْ تَجِدَ مِنْ دُونِهِ مُلْتَحَدًا ٢٧
And recite (and teach) what has been revealed to thee of the Book of thy Lord: none can change His Words, and none wilt thou find as a refuge other than Him.
