Najasa (Impurity)

Islamic Laws

I am not sure if the ground at my school is Najis and sometimes in PE outside or during break I sit on the ground. Do my clothes or part of my body become impure? Sayyed Mohammad Al-Musawi	When any part of our body or cloth is impure can we freely touch the impure area while doing our routine work even if sweat comes on our hands or body and touches those impure areas? Sayyed Mohammad Al-Musawi
Can a vet do Wudhu and pray on time while being in a state of impurity due to handling of dogs or does he have to wait to get back home and bathe and pray all the Qadha namaz together? Sayyed Mohammad Al-Musawi	I was impure before the start of Ramadan and did not know that I had to do Ghusl and fasted throughout the whole month. Are my fasts still valid or will I have to make them up? Sayyed Mohammad Al-Musawi
