Assalam o Alaikum.
often it happens that i feel that gas might have been released during Salah. I know that in such a case of doubt , Prophet Muhammad (sallallahu alaihi wasallam ) ordered to not leave the Salah unless one hears a sound or finds a smell. I am probably an OCD type person and sometimes i feel that i do find a smell but its very vague and maybe from my imagination. It does not exactly seem like the smell of gas/fart. In such case, should i continue my Salah?
