Does doubting about passing gas during namaz makes it baatil? Because I have been this issue of doubt for few years and I always redo my namaz about 5 times.

I dont know if I really have a illness or its just shaytan that disturb me.
I already did a treatment and take medicine but its the same problem

I know the importance of salat , and i am always trying to pray at time but this problem just make me really sad , because I am really scared if its the fact that Allah (swt) don’t want to listen my voice? I dont know what to do. This really breks my heart
I still making many duas, isteghfar and seek help from the Ahlul Bayt(as) ..

Doubt has no worth only that gas invalidate the wudhu which Passing from the rear. If one hears the sound from stomach or intestine it does not invalidate the wudhu.
Please pay attention before the prayer that really it is gas or doubt. Once it is confirmed that it is not gas then wudhu is correct and in order. If it is gas then yes wudhu is batil. But again I’m saying do no give importance to doubts.
