Arabic works without the harakāt — type البقرة or baqarah.
No surah matches that.

Tahlīl al-Kalimāt
Not a commentary: every word tagged with its root, its part of speech and its case.
And those who are taken in death among you and leave wives behind - for their wives is a bequest: maintenance for one year without turning [them] out. But if they leave [of their own accord], then there is no blame upon you for what they do with themselves in an acceptable way. And Allah is Exalted in Might and Wise.
The same ayah, in another commentary
Al-Baqarah 2:240
