Question: Assalam alaykum
If my saliva happens to exit my mouth and lands on my lips and then that saliva happens to enter my mouth again during the prayer, then is my prayer nullified if I swallow that saliva?
Answer: Assalamu alaikum wa rahmatullah,
No, your prayer is not invalidated by swallowing the saliva on your lips.
This is because the general basis is that if it does not affect the validity of a fast, it does not invalidate your prayer. Hypothetically, if the saliva on your lips was problematic, then you would need to be sure of having swallowed the exact same saliva. In any case, misgivings are to be ignored.
The Messenger of Allah (Allah bless him and give him peace) said, “Verily this religion is ease, and nobody makes it difficult except that it overwhelms them.” [Bukhari]
