Al-Kahf · 18:82

82. As for the wall which I fixed but you criticised me for fixing, it belonged to two young boys in the town we went to and whose father had passed away. Beneath the wall some wealth of theirs was buried. And the father of these two boys was pious. So your Lord intended, O Moses, that they reach the age of discerning and grow up, and take out their wealth which was buried underneath it, because if the wall were to fall now, their wealth would become exposed and go to waste. And this plan was your Lord’s mercy on them. And I did not do this of my own judgment. This is the explanation of what you were unable to bear”.
