Ref. No. 2548/45-3886
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
(1) The water coming out of the private parts is impure. If it gets on the clothes, the clothes become impure. However, it is not obligatory for you to perform ghusl, but it is sufficient to wash the private part and the portion of the clothes where the impurity existed. (2) If the amount of impurity is more than one dirham (coin), it is necessary to wash the clothes. Even if it is dried up, it is not permissible to wear it and pray without washing away the impurity. It will be necessary to wash the area. (3) If there was impurity in the organ and it was washed and purified in the sink, the sink was also purified, it is not necessary to wash it separately, but for comfort, one should wash it again and perform ablution in that place.
