Tum'a: Praying if No Water for Handwashing

If there is no water to wash hands, even after sleeping, you still say blessings and prayers. You should say asher yatzar even if you can't wash, but do not say al netilat yadayim in shacharit!
Note Even if you do not have water with which to wash your hands, you should wipe them off on a towel or some substance that can rub off any physical impurities that you may have gotten on them while sleeping.
