Is there a difference between a little showing off and a lot of it in invalidating the act of worship?

Question:
He says: Honorable Shaykh, may Allah grant you success, is there a difference between a little showing off and a lot of it in the issue of invalidating the act of worship?

Answer:
There is no difference in that. Showing off, whether much or little, if it enters into the act of worship, it corrupts it, except if he repents. The Muslim makes up for it and returns to Allah and repents. This is a point of disagreement: does the rest of his work become invalid or not? Ibn Rajab mentioned the issue in his commentary on the Forty Hadiths in *Jami' al-'Ulum wa al-Hikam*, and it appears he holds that if he repents and returns, his work remains, both its beginning and its end. Yes.
