What is the ruling on the prayer of one who misses it due to continuous gas from Maghrib until 'Isha? And how are these prayers to be made up? And is there any sin incurred for that?

"Abandoning prayer is a grave error. The prescribed action is to wait for the gas discharge to stop, then perform the Maghrib and Isha prayers. According to the Maliki school, the time for Maghrib extends, in cases of necessity, until Fajr. For those with valid excuses, it extends similarly according to the Shafi'i school. One must immediately make up for missed prayers. We hope that you will not be sinful due to ignorance."
