my clothes are not clean, now if i wash that particular place of my clothes the clothes will become clean or not ?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

If you only wash the impure spot on your clothes then they become pure. It is not required to wash them entirely, as washing the impure spot only is the obligation.

Allaah Knows best.
