Arabic works without the harakāt — type البقرة or baqarah.
No surah matches that.
الدر المصون
As-Samīn al-Ḥalabī
Every word parsed. The standard work on the grammar of the Qur'an.
And as for the wall, it belonged to two orphan boys in the city, and there was beneath it a treasure for them, and their father had been righteous. So your Lord intended that they reach maturity and extract their treasure, as a mercy from your Lord. And I did it not of my own accord. That is the interpretation of that about which you could not have patience."
The same ayah, in another commentary
Al-Kahf 18:82
