Sura al-Kahf 18:17

وَتَرَى ٱلشَّمْسَ إِذَا طَلَعَت تَّزَٰوَرُ عَن كَهْفِهِمْ ذَاتَ ٱلْيَمِينِ وَإِذَا غَرَبَت تَّقْرِضُهُمْ ذَاتَ ٱلشِّمَالِ وَهُمْ فِى فَجْوَةٍ مِّنْهُ ذَٰلِكَ مِنْ ءَايَٰتِ ٱللَّـهِ مَن يَهْدِ ٱللَّـهُ فَهُوَ ٱلْمُهْتَدِ وَمَن يُضْلِلْ فَلَن تَجِدَ لَهُۥ وَلِيًّا مُّرْشِدًا

wa-tara l-shamsa idhā ṭalaʿat ttazāwaru ʿan kahfihim dhāta l-yamīni wa-idhā gharabat ttaqriḍuhum dhāta l-shimāli wa-hum fī fajwatin minhu dhālika min āyāti allāhi man yahdi allāhu fa-huwa l-muhtadi wa-man yuḍlil fa-lan tajida lahu waliyyan murshidan

Thou wouldst have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the open space in the midst of the Cave. Such are among the Signs of Allah: He whom Allah, guides is rightly guided; but he whom Allah leaves to stray,- for him wilt thou find no protector to lead him to the Right Way.

Sura al-Kahf 18:90

حَتَّىٰٓ إِذَا بَلَغَ مَطْلِعَ ٱلشَّمْسِ وَجَدَهَا تَطْلُعُ عَلَىٰ قَوْمٍ لَّمْ نَجْعَل لَّهُم مِّن دُونِهَا سِتْرًا

ḥatta idhā balagha maṭliʿa l-shamsi wajadahā taṭluʿu ʿalā qawmin lam najʿal lahum min dūnihā sitran

Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun.
