(7) Chapter: When the first ten days of Dhul-Hijjah begin, it is forbidden for the one who wants to offer a sacrifice to remove anything from his hair, nails or skin
Umm Salama, the wife of Allah’s Apostle (ﷺ), reported Allah’s Messenger (ﷺ) to have said:
He who has a sacrificial animal with him whom (he intends) to offer as sacrifice, and he enters the month of Dhu’I-Hijja, he should not get his hair cut or nails trimmed until he has sacrificed the animal.
