The eminent Muslim scholar and renowned Da`iyah, Sheikh `Abdel Khaliq Hasan Ash-Shareef, states: “There is nothing in the sources telling that if clothes got stuck with urine or madhi, then they should be washed three times and also to be squeezed after each time. To remove such impurities, such clothes which got stuck by urine, madhi or mani must be only washed.”
So, it is incorrect to say that the clothes which got stuck with urine or madhi must be washed three times and clothes which got stuck with mani must be washed one time. There is no specific details for the methods of washing which are left to people’s sense of observing general health and cleanliness. What is import is to remove such impurities so that you can perform Prayer wearing them.
