Al Kahf Ayah 21

وَكَذَٲلِكَ أَعْثَرْنَا عَلَيْهِمْ لِيَعْلَمُوٓاْ أَنَّ وَعْدَ ٱللَّهِ حَقٌّ وَأَنَّ ٱلسَّاعَةَ لَا رَيْبَ فِيهَآ إِذْ يَتَنَـٰزَعُونَ بَيْنَهُمْ أَمْرَهُمْ‌ۖ فَقَالُواْ ٱبْنُواْ عَلَيْهِم بُنْيَـٰنًا‌ۖ رَّبُّهُمْ أَعْلَمُ بِهِمْ‌ۚ قَالَ ٱلَّذِينَ غَلَبُواْ عَلَىٰٓ أَمْرِهِمْ لَنَتَّخِذَنَّ عَلَيْهِم مَّسْجِدًا ٢١ That is how We caused them to be discovered so that their people might know that Allah’s promise ?of resurrection? is true and that there is no doubt about the Hour. When the people disputed with each other about the case of the youth ?after their death?, some proposed, “Build a structure around them. Their Lord knows best about them.” Those who prevailed in the matter said, “We will surely build a place of worship over them.”
