Al-Kahf 18:21

This is how We made their case known so that the people might know that the promise of Allah is true and that there is no doubt about the Hour. When they were disputing among themselves[13] concerning their matter [of resurrection], they said, “Build a structure over them. Their Lord knows best about them.” Those who prevailed in their matter said, “We will surely build over them a place of worship.”

[13] i.e., the inhabitants of the city.

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 they[783] 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."[784]

[783] The people of the city.
[784] i.e., we will make this site a place of worship.

21. And thus We made their case known (to the people), that they might know that the Promise of Allâh is true, and that there can be no doubt about the Hour. (Remember) when they (the people of the city) disputed among themselves about their case, they said: "Construct a building over them; their Lord knows best about them;" (then) those who won their point said (most probably the disbelievers): "We verily shall build a place of worship over them."

And 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.
