Quran 18, Al-Kahf (The Cave) ⓘ

18:21And in like manner We disclosed them (to the people of the city) that they might know that the promise of Allah is true, and that, as for the Hour, there is no doubt concerning it. When (the people of the city) disputed of their case among themselves, they said: Build over them a building; their Lord knoweth best concerning them. Those who won their point said: We verily shall build a place of worship over them.

وَكَذَلِكَ أَعْثَرْنَا عَلَيْهِمْ لِيَعْلَمُوا أَنَّ وَعْدَ اللَّهِ حَقٌّ وَأَنَّ السَّاعَةَ لَا رَيْبَ فِيهَا إِذْ يَتَنَازَعُونَ بَيْنَهُمْ أَمْرَهُمْ فَقَالُوا ابْنُوا عَلَيْهِمْ بُنْيَانًا رَبُّهُمْ أَعْلَمُ بِهِمْ قَالَ الَّذِينَ غَلَبُوا عَلَى أَمْرِهِمْ لَنَتَّخِذَنَّ عَلَيْهِمْ مَسْجِدًا
