Arabic works without the harakāt — type البقرة or baqarah.
No surah matches that.
تحليل كلمات القرآن
Tahlīl al-Kalimāt
Every word tagged with its root, its form and its case.
And [He also forgave] the three who were left behind [and regretted their error] to the point that the earth closed in on them in spite of its vastness and their souls confined them and they were certain that there is no refuge from Allah except in Him. Then He turned to them so they could repent. Indeed, Allah is the Accepting of repentance, the Merciful.
The same ayah, in another commentary
At-Tawbah 9:118
