Arabic works without the harakāt — type البقرة or baqarah.
No surah matches that.
تفسير القرآن
Al-Samʿānī
Short and steady — the plain meaning, with the reports that bear on it and little else.
Allah has sent down the best statement: a consistent Book wherein is reiteration. The skins shiver therefrom of those who fear their Lord; then their skins and their hearts relax at the remembrance of Allah. That is the guidance of Allah by which He guides whom He wills. And one whom Allah leaves astray - for him there is no guide.
The same ayah, in another commentary
Az-Zumar 39:23
