Question:
This questioner asks: Is a bid'ah (religious innovation) that does not amount to disbelief greater than major sins?

Answer:
Yes, bid'ah (religious innovation) is evil; bid'ah (religious innovation) is evil. It is more beloved to Iblis than sin; it is more beloved to Iblis than zina (unlawful sexual intercourse), theft, and killing the soul. Bid'ah (religious innovation) is more beloved to him than these major sins. We ask Allah for well-being, because He knows that it leads to kufr (disbelief), shirk (associating partners with Allah), and extremism. Unlike sins, where the one who commits them regrets and repents. The one who commits bid'ah (religious innovation) does not repent because he sees that he is on the right. Yes.
