Which is more severe, bid'ah (religious innovation) or sin?

Question:
The questioner says: Is bid'ah (religious innovation) more severe than sin?

Answer:
Bid'ah (religious innovation) is more severe and more beloved to Satan than sin. This is because the one who commits a sin does so while knowing that he is a sinner, but his desire or his passion overcame him, and he knows that he is a sinner. It is hoped that he will repent, because as long as he knows that he is a sinner, it is hoped that he will repent. This is unlike the innovator, who sees that he is on the right path; he sees that he is on the right path. Therefore, he does not repent. So, few of the innovators repent, unlike the sinners, for many of them repent and return to Allah (Glorified and Exalted is He). Yes.
