well, wudhu could be done. infact, most ppl in my village perform wudhu n all before preyers.. but the main point of wudhu is to be clean rite?? so if we r already clean, then theres no need to do wudhu.. but if we r not clean, then we hav to clean all the parts that r unclean before we can pray.. whatever the quran tells us to clean, we hav to clean it.. i don't remember the ayah but can u post it where it mentions abt wudhu so that i can explain more... thanx in advance..
thanks for answer. that ayat is 5:6 (almaida verse 6). but this clearly says that we have to do wudhy before each salat unless you are already in wudhu. apparently you may be clean but still you have to do wudhu.
