Do the pricks, throbs, or bubbles felt in one's anus, which recur during ablution or prayer, nullify ablution as gas, or is it something else, or from Satan, or a disease that necessitates repeating ablution?

The emission of wind (flatulence) invalidates ablution, whether it produces a sound or not, if its expulsion is certain. However, mere doubt holds no weight, due to the Prophet's (peace and blessings be upon him) saying: "He should not leave (the prayer) until he hears a sound or perceives an odor." Therefore, whoever is certain of their ritual purity and doubts its invalidation, is judged to remain in a state of purity.
