Kindness to his parents helpful

وَأَمَّا ٱلْجِدَارُ فَكَانَ لِغُلَٰمَيْنِ يَتِيمَيْنِ فِى ٱلْمَدِينَةِ وَكَانَ تَحْتَهُۥ كَنزٌۭ لَّهُمَا وَكَانَ أَبُوهُمَا صَٰلِحًۭا فَأَرَادَ رَبُّكَ أَن يَبْلُغَآ أَشُدَّهُمَا وَيَسْتَخْرِجَا كَنزَهُمَا رَحْمَةًۭ مِّن رَّبِّكَ ۚ وَمَا فَعَلْتُهُۥ عَنْ أَمْرِى ۚ ذَٰلِكَ تَأْوِيلُ مَا لَمْ تَسْطِع عَّلَيْهِ صَبْرًۭا

"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."
