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

بسم اللہ الرحمن الرحیم

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 one of you wants to offer an Ud-hiyah, let them refrain from (cutting anything) from their hair or nails.

According to the version narrated by Abu Dawud which was also narrated by Muslim and Al-Nasa’y:

Anyone who has an Ud-hiyah to slaughter, when the new moon of Dhul-Hijjah appears, should not remove 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.
