Allah says: “And do not shave your heads until the offering reaches the place of sacrifice.” (Qur’an 2.196)
There is consensus among the scholars that a person in the state of ihram is forbidden to clip his fingernails without any genuine excuse. However, if a nail is broken, one may remove it without incurring any penalty.
Removing the hair is permitted, if it becomes bothersome. In such a case one must pay atonement, except for the removal of hair of the eye if it bothers him. (The Maliki scholars hold there is a penalty for removing hair of the eyes) Allah the Almighty says: “And if any of you is ill, or has an ailment in his scalp (necessitating shaving), he should in compensation either fast, or feed the poor, or offer sacrifice.” (Qur’an 2.196) This will be discussed later.
