If you want to offer a sacrifice and the month of Dhul Hijjah has begun, then it is haram for you to remove anything of your hair or nails or skin until you have slaughtered the sacrifice. It is permissible for your family to remove things from their hair, nails and skin during the first ten days of Dhul Hijjah.

If the onset of Dhul Hijjah has been proven and a person wants to offer a sacrifice, it is haram for him to remove anything from the hair on his body or to cut his nails or any part of his skin.

Some scholars view that udhiyah is prescribed for pilgrims– whether they regard it as recommended or obligatory. Other scholars maintain that udhiyah is not prescribed for pilgrims.

Whoever removes something from his hair, nails or skin during the first ten days of Dhul Hijjah out of forgetfulness or ignorance of the ruling, when he has resolved to offer a sacrifice, does not have to do anything.
