How can a woman rid herself of sexual obsessions that occur to her during prayer, and must she interrupt her prayer every time she experiences these obsessions?

The treatment for obsessive thoughts (waswasah) involves strengthening faith, increasing acts of obedience, remembrance (dhikr), seeking forgiveness (istighfar), and turning to Allah. Among the most beneficial ways to treat it is to ignore it and to struggle against oneself not to pay attention to it. The person afflicted with waswasah must know that they are not held accountable for the thoughts that cross their mind as long as they dislike them. Also, one must avoid things that provoke obsessive thoughts, such as watching lewd films and pictures. Furthermore, one should relieve oneself before prayer whenever possible and if there is sufficient time for the obligatory prayer.
