Wudu Ghusl Realisation Afterwards Of Missed Spots
If you are sue that a spot is missed from a mandatory part of body to wash, you need to wash only that spot. If you have offered the prayer before, and time for prayer is still not over, you need to repeat it. but if time is over, you may repeat the prayer but y you are not obliged to do so. if such thigs happens to someone often, it may be delusional. Need not to worry about it.
