The Ruling on Waswas (Obsessive Doubts) in Wudu'

Question:
Several questions regarding waswas (obsessive doubts) in wudu', as well as waswas regarding the passing of wind.

Answer:
If waswas and doubt become frequent, one should not pay attention to them. If the doubt arises after completing the act of worship, whether it is wudu' or prayer, one should not pay attention to it unless he is certain, if he becomes certain. If the doubt is sudden, he should investigate. He develops a doubt: Did he complete the wudu'? Did he wash this limb? Did he do such and such? He investigates until something becomes more likely in his mind, or he builds upon certainty, which is according to his situation. If he started the wudu' and washed his feet, the default is the completeness of purity, because a limb may dry quickly if there is intense heat or strong wind. The point is that a person does not pay attention to waswas in two cases: first, when it becomes frequent, and second, when he has finished the act of worship, he does not pay attention to it until he is certain of a deficiency. As for anything other than that, he investigates. If he develops a doubt, he investigates, trying to recall, perhaps something will become more likely in his mind, or he builds upon certainty. Yes.
