‏السلام عليكم ورحمة الله وبركاته ‏أحسن الله إليك How to deal with riya thoughts? ‏بارك الله فيك

Ignore them and continue doing goodness; in fact, exaggerate in doing goodness. Don't pay attention to waswas (evil thoughts) that are trying to tell you that you're not doing this for the sake of Allah just to make you stop. Continue in goodness and ignore them.
