If some difficulty arises after entering the state of Ihram for the Hajj or Umra (i.e., illness, resistance by enemy to prevent from reaching Mecca) then the sacrifice of an animal should be offered and the Ihram removed. We read in the Holy Quran: “ … but if you are kept back, then make whatever offering is easily available; and do not shave your heads until the offering reaches its destination … “ (2:197).
