QUESTION:
I would like to know that when a person makes wudu, after wudu if he changes clothes, does he have to repeat the wudu again?
ANSWER:
Changing clothes after you have performed wudu does not invalidate the ablution, therefore you are not required to repeat it again.
Wudu is invalidated only when:
1. Anything exits from the two private parts of the body.
2. Impure substances such as blood or pus flow from their point of exit and encroach on a place which it is incumbent to purify.
3. Vomiting, if it was a mouthful (this is determined by whether you were able to keep your mouth closed or not)
4. Sleeping lying down so that the rear is not firmly seated, or leaning [on one’s side] or reclining on something such that if it were removed he would fall.
5. Loss of consciousness through fainting or insanity.
6. Laughter in any prayer containing ruku` and sujud.
