Answered by Ustadh Tabraze Azam
Is it recommended for the person performing the ritual slaughter (udhiya/qurbani) to abstain from cutting their hair and nails? I have seen hadiths going against it.
It is recommended for the person performing the ritual slaughter (udhiya/qurbani) to abstain from cutting their hair, nails and the like until after the sacrifice has taken place. However, doing otherwise is not disliked (makruh).
There are clear traditions (hadith) in which the Prophet (Allah bless him and give him peace) instructed avoiding such personal upkeep before the sacrifice, but given that we have Prophetic precedence in not doing so, the command is considered to be for a recommendation.
‘A’isha (may Allah be well pleased with her) said, “I used to plait the garlands of the sacrificial camels of the Messenger of Allah (Allah bless him and give him peace). He would send his camels to the Ka‘ba, but nothing was unlawful to him which is lawful for a man to do with his wife until the people returned.” [Bukhari]

And Allah Most High alone knows best.
