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.
So if they deny you, [O Muhammad], say, "Your Lord is the possessor of vast mercy; but His punishment cannot be repelled from the people who are criminals."
Those who associated with Allah will say, "If Allah had willed, we would not have associated [anything] and neither would our fathers, nor would we have prohibited anything." Likewise did those before deny until they tasted Our punishment. Say, "Do you have any knowledge that you can produce for us? You follow not except assumption, and you are not but falsifying."
Say, "With Allah is the far-reaching argument. If He had willed, He would have guided you all."

Al-Anʿām 6:147
