Al-Kahf 18:21 وكذالك اعثرنا عليهم ليعلموا ان وعد الله حق وان الساعة لا ريب فيها اذ يتنازعون بينهم امرهم فقالوا ابنوا عليهم بنيانا ربهم اعلم بهم قال الذين غلبوا على امرهم لنتخذن عليهم مسجدا ٢١
وَكَذَٰلِكَ
أَعۡثَرۡنَا
عَلَيۡهِمۡ
لِيَعۡلَمُوٓاْ
أَنَّ
وَعۡدَ
ٱللَّهِ
حَقّٞ
وَأَنَّ
ٱلسَّاعَةَ
لَا
رَيۡبَ
فِيهَآ
إِذۡ
يَتَنَٰزَعُونَ
بَيۡنَهُمۡ
أَمۡرَهُمۡۖ
فَقَالُواْ
ٱبۡنُواْ
عَلَيۡهِم
بُنۡيَٰنٗاۖ
رَّبُّهُمۡ
أَعۡلَمُ
بِهِمۡۚ
قَالَ
ٱلَّذِينَ
غَلَبُواْ
عَلَىٰٓ
أَمۡرِهِمۡ
لَنَتَّخِذَنَّ
عَلَيۡهِم
مَّسۡجِدٗا

And similarly, We caused them to be found that they [who found them] would know that the promise of Allāh is truth and that of the Hour there is no doubt. [That was] when they1 disputed among themselves about their affair and [then] said, "Construct over them a structure. Their Lord is most knowing about them." Said those who prevailed in the matter, "We will surely take [for ourselves] over them a masjid."2
