Doubts about whether some drops of urine have fallen on clothes
Question

It happens that after I have cleaned myself (after passing water) and done Wudu, I feel some drops of urine come out, which makes me repeat my wudoo, sometimes twice. After the urine has come out, I wait for five minutes until I am sure that it has stopped, but after I finish Wudu, I feel that a few small drops of urine have come out of me. I am trying to solve this problem so that I will have no doubts at all. If it happens that a few drops of urine get onto my clothes, do I have to wash it? If this happens, does it invalidate my prayer? Sometimes I start washing my trousers because I am not sure whether there are any drops of urine on them.
Praise be to Allah.If you are certain that some drops of urine have come out, then you have to clean yourself again and repeat your Wudu for each prayer, and you have to wash off whatever urine has got onto your clothes. But if there is some doubt, you do not have to do that. You should not pay attention to doubts, lest you fall prey to waswaas (insinuating thoughts from Shaytaan).
