A: A person who intends to offer Ud-Hiyah should not get his hair or skin hair cut or his nails trimmed after the first day of Dhul-Hijjah until he offers his Ud-Hiyah. It has been narrated by the Six Hadith Compilers (Muslim, Abu Dawud, Al-Tirmidhy, Al-Nasa'y, and Ibn Majah) except for Al-Bukhari (may Allah be Merciful with them) on the authority of Um Salamah (may Allah be pleased with her) that the Messenger of Allah (peace be upon him) said, If anyone has in his possession a sacrificial animal to offer as a sacrifice (on `Eid-ul-Adha), he should not get his hair cut and nails trimmed after he has entered the first days of Dhul-Hijjah. And the wording of the narration of Abu Dawud, Muslim and Al-Nasa'y is: Anyone who has a sacrificial animal meant to be offered as sacrifice, and he enters the month of Dhul-Hijjah should not get his hair cut or nails trimmed until he has sacrificed the animal. (Part No. 11; Page No. 398) This rule applies whether he slaughters it himself or authorizes someone else to slaughter it for him. As for those who will authorize someone to slaughter on their behalf, they should not abide by the acts forbidden for pilgrims during the first ten days of Dhul-Hajjah because there is no reported text in this regard. This is not Ihram, for the Muhrim is the one who intends to perform Hajj or `Umrah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
