Is it permissible to complete the prayer upon feeling something exit without sound or odor? Is it permissible to prevent the exit of wind (gas) during prayer? What should one do when the exit of wind is continuous, leading to missing congregational prayers at Fajr and Maghrib? And should the worshiper bow with the Imam if the Imam is quick and the worshiper has not completed Al-Fatiha?

The sensation of something exiting is merely a whisper (waswasah); do not pay attention to it. However, if you are certain, with firm conviction, that something has exited, then your prayer is invalidated, and you must exit it, perform ablution (wudu'), and restart it. Suppressing flatulence during prayer is permissible, and whoever experiences this during their prayer should continue with it. As for someone who believes the event (hadath) will persist until the prayer's time expires, their ruling is the same as that of a person with chronic incontinence (sals); they perform ablution after the prayer time begins, and pray with that ablution the obligatory prayer and as many voluntary prayers as they wish until the time expires.
