Is it permissible to perform ghusl for janabah with the intention of also removing minor impurity if there is a discharge of urine drops that lasts for twenty minutes, and is wudu required after ghusl in this case?

If someone performs ghusl (definition) (ritual bath) for janabah (definition) (major ritual impurity) and intends thereby to remove both minor and major ritual impurities, that is sufficient for him. He is permitted to pray with that purification as long as it is not invalidated. If a drop of urine exits after purification, it necessitates washing whatever part of the garment and body it touched, and re-performing wudu' (ablution) only. It is advisable not to pay attention to this feeling, fearing obsessive doubts (waswasah). It is not obligatory to search or squeeze the penis after relieving oneself. The jurists have mentioned the recommendation of sprinkling water on the private parts or trousers after istinja (definition)' (cleaning oneself after relieving oneself) to ward off obsessive doubts. If one doubts whether something has exited after istinja', one should not pay attention to it, as it is from Satan.
