'And what' means while it is the case that 'no one denies it except every transgressor.' This means a person who exceeds the limit in stubbornness or rigidity and imitation. This is because the basis for the attribution of one who has been established by decisive proofs that He is capable of all things leads to the inability to repeat what He has initiated. 'A sinful one' means one who is excessive in indulging in desires that lead to sins, which are the wrongdoings. His heart has turned black, and he has become blind to the desires that are surrounded by the Fire, away from anything else.
