Arabic works without the harakāt — type البقرة or baqarah.
No surah matches that.
بحر العلوم
Al-Samarqandī
One of the earliest. The plain sense, then the main opinions.
Those are the ones who have purchased error [in exchange] for guidance, so their transaction has brought no profit, nor were they guided.
Their example is that of one who kindled a fire, but when it illuminated what was around him, Allah took away their light and left them in darkness [so] they could not see.
Deaf, dumb and blind - so they will not return [to the right path].
The same ayah, in another commentary
Al-Baqarah 2:16
