Surah Al-Kahf (The Cave), Verse 82

وَاَمَّا الْجِدَارُ فَكَانَ لِغُلٰمَیْنِ یَتِیْمَیْنِ فِی الْمَدِیْنَةِ وَكَانَ تَحْتَهٗ كَنْزٌ لَّهُمَا وَكَانَ اَبُوْهُمَا صَالِحًا فَاَرَادَ رَبُّكَ اَنْ یَّبْلُغَاۤ اَشُدَّهُمَا وَیَسْتَخْرِجَا كَنْزَهُمَا رَحْمَةً مِّنْ رَّبِّكَ وَمَا فَعَلْتُهٗ عَنْ اَمْرِیْ ذٰلِكَ تَاْوِیْلُ مَا لَمْ تَسْطِعْ عَّلَیْهِ صَبْرًا ۟

“"As for the wall, it belonged to two youths, orphans, in the Town; there was, beneath it, a buried treasure, to which they were entitled: their father had been a righteous man: So thy Lord desired that they should attain their age of full strength and get out their treasure - a mercy (and favour) from thy Lord. I did it not of my own accord. Such is the interpretation of (those things) over which thou wast unable to hold patience."”
