Arabic works without the harakāt — type البقرة or baqarah.
No surah matches that.
الإعراب الميسر
Al-Iʿrāb al-Muyassar
What each word is, in a line. The short answer.
O mankind, worship your Lord, who created you and those before you, that you may become righteous -
[He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him].
And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful.
The same ayah, in another commentary
Al-Baqarah 2:21
