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

When any one of you intending to sacrifice the animal enters in the month (of Dhu'l-Hijja) he should not get his hair or nails touched (cut). It was said to Sufyan that some of the (scholars) did not deem this hadith to be Maffu'. He said: But I deem it as Marfu' (i. e. chain of narration traceable right up to the Holy Prophet).

If anyone of you intends to offer sacrifice he should not get his hair cut or nails trimmed.

If anyone has in his possession a sacrificial animal to offer as a sacrifice (on 'Id al-Adha), he should not get his hair cut and nails trimmed after he has entered the first days of Dhu'l Hijja

This hadith has been narrated on the authority of 'Amr b. Muslim with the same chain of transmitters.

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.

While we were in a bathroom just before 'Id al-Adha some of the persons tried to remove the hair with the help of hair-removing chemicals. Thereupon some of the people owning the bath (or some of the people sitting therein) said that Sa'id b. Musayyib did not approve of it, or he prohibited it. Then I met Sa'id b. Musayyib and made a mention of that to him, whereupon he said: O my nephew, this is the hadith which has been forgotten, and abandoned. Umm Salama, the wife of Allah's Apostle (ﷺ), narrated to me Allah's Messenger (ﷺ) having said as narrated above.

Amr b. Muslim al-Jundani reported that Ibn Musayyib had told him that it was Umm Salama, the wife of Allah's Apostle (ﷺ), who had informed him of that as narrated above.
