Is seeking forgiveness and glorifying God while committing a sin forbidden, or is the Muslim rewarded for it, and is there a difference of opinion regarding its ruling?

Scholarly opinions differ regarding the ruling on the remembrance of Allah during the commission of a sin. Some hold that the Basmalah is a form of remembrance and a good deed, so it is not forbidden to utter it, but it is disliked due to its proximity to a prohibited act. The ruling on remembering Allah in this situation varies depending on the person's state and what is in their heart. If one remembers Allah with fear and awe, hoping for His mercy, and seeking repentance, they may be rewarded for their remembrance, and it becomes a good deed mixed with their sins, with hope for Allah's grace and acceptance. However, if their heart is heedless and they are contemptuous of the sin, then remembrance will not benefit them.
