Washing the Necessary Parts
Question :

If one thought that he was washing the necessary parts of the wudhu, but years later realized that he had been missing some of them, is it obligatory on him to repeat all of those prayers that he performed with this wudhu?

Answer :

If one doubts the correctness of the wudhu but at the same it is probable that he washed the necessary parts without intending to do so, then he can assume that the wudhu is in order and he does not need to repeat the prayer. If he knows that he did not wash a necessary part of the wudhu, then it is invalid and he must repeat the prayers that he performed with such wudhu.

Doubts in Washing Properly
Question :

During wudhu, I always become doubtful as to whether I am doing the washing properly e.g. whether or not I am wiping my arms in a manner where it is reaching everywhere, which leads me to be very meticulous in my wudhu. May I ignore this doubt?

Answer :

If the doubt is conventionally normal, and not a type of waswasah, one should pay attention to it, and therefore wash until he is certain that during the washings the water has reached all parts of the face or arm. If the doubt is a type of waswasah, then one should ignore it.

Definition of Waswasa
Question :

The problem with people with waswasa in wudhu is that they do not distinguish between waswasa and normal doubt. So how can one define waswasa so it can be ignored?

Answer :

One can recognize waswasa by some signs, like when one is having his doubts in situations much more than other people in similar situations. Also, one can determine it when his inner feeling is that the religious worship is correct, but he still has worries and tensions that prevent him from accepting his internal certainty.

Doubts in Washing the Face
Question :

If I doubt whether I washed the face in wudhu or not while washing my arms, do I have to restart the wudhu?

Answer :

If this was an excessive doubt, arising out of waswasa, then one should ignore it. If this was a regular doubt, one should go back to wash the face and continue from there.

Doubt in Invalidating Wudhu
Question :

Sometimes during my prayers, I feel like I've passed gas but am not completely sure whether it should be considered as breaking wind; what is the ruling in the said case?

Answer :

With the doubt of passing wind, you can assume that the wudhu and the prayer are in order.

Excessive Doubts
Question :

I have excessive doubts about my past acts of worship, such as my wudhu and ghusl, and even my Hajj pilgrimage, even though I believe I know and follow the laws of the Sharia for these acts of worship. Can you please guide me on what I should do regarding these doubts?

Answer :

Do not pay attention to such doubts. You can assume that all acts of worship that you have performed were correct and valid.
