Arabic works without the harakāt — type البقرة or baqarah.
No surah matches that.
إعراب القرآن الكريم
Ad-Daʿʿās
A close, unhurried parse — word by word, and nothing else.
O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] determination.
And do not turn your cheek [in contempt] toward people and do not walk through the earth exultantly. Indeed, Allah does not like everyone self-deluded and boastful.
And be moderate in your pace and lower your voice; indeed, the most disagreeable of sounds is the voice of donkeys."
The same ayah, in another commentary
Luqmān 31:17
