What is the ruling on demolishing shrines, and what should I do if I pass wind while in the first row during congregational prayer?

Building shrines and domes over tombs and elevating graves are reprehensible acts that must be avoided and denounced, based on the Prophet's (peace be upon him) saying to Ali (may Allah be pleased with him): "Do not leave any image without effacing it, nor any elevated grave without leveling it." These structures must be demolished whenever possible, because they constitute an evil that must be changed by whoever is able, provided that it does not lead to a greater evil. As for someone whose ablution is invalidated or who remembers it during prayer, he must exit the prayer, perform ablution, and repeat the prayer anew, because ablution is a condition for the validity of prayer.
