Whoever wants to offer an Ud-hiyah should not cut his hair or trim his nails

A: The wording which we know for this Hadith is not as mentioned by the questioner. The wording which we know to be authentically reported from the Prophet (peace be upon him) is the one narrated by five out of the six Compilers of Hadith (Muslim, Ibn Majah, Abu Dawud, Al-Tirmidhy and Al-Nasa’y, except Al-Bukhari) on the authority of Um Salamah (may Allah be pleased with her) that the Messenger of Allah (peace be upon him) said: When you see the new moon of Dhul-Hijjah and any of you wants to offer an Ud-hiyah, let them refrain from cutting anything from their hair or nails. According to the version related by Abu Dawud that was also related by Muslim and Al-Nasa'y: Anyone who has an Ud-hiyah to slaughter, when the new moon of Dhul-Hijjah appears, should not cut anything from their hair or nails until they have offered the Ud-hiyah. This Hadith indicates that a person who wants to offer an Ud-hiyah is not allowed to remove anything from their hair or nails after the first Ten Days of Dhul-Hijjah begin. (Part No. 11; Page No. 427) The first report constitutes a command to refrain, which basically implies that refraining is obligatory, and we do not know of any reason to interpret it otherwise. The second report constitutes a prohibition from removing anything, which basically implies that it is Haram (forbidden), and we do not know of any reason to interpret it otherwise. Thus, it is clear that this Hadith applies only to a person who wants to offer Ud-hiyah. As for a person on whose behalf the Ud-hiyah is being offered, whether old or young, they are not forbidden to remove anything from their hair, skin, or nails, based on the basic principle, which is that these actions are permissible. We do not know of any evidence to the contrary.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions.
