What is the authenticity of the hadith: “Whoever intends to offer a sacrifice should not take from his hair”?

Question:
What is your opinion regarding the hadith: and the hadith: Does this apply to the pilgrim and the non-pilgrim? Or is it obligatory for the resident and not the pilgrim? Since the questioner, when he resolved to perform Hajj on the eighth day of Dhul-Hijjah, shaved—meaning he trimmed his mustache and removed his armpit hair—fearing that he would not be able to do so at the miqat due to the long distance, and since the questioner appointed someone to offer the sacrifice on behalf of his family, is there anything required of him in this? And what is the best course of action regarding the two mentioned hadiths? And what is required of him if he offers the sacrifice on the second day after the festival?

Answer:
The first is not a hadith; rather, it is the statement of some scholars. When one reaches the miqat, he should clean himself, taking from his mustache, armpits, and the like. This is not a hadith; it is the statement of some scholars, as we said that it is recommended for one who intends to perform 'Umrah or Hajj to clean himself, trim his mustache, and cut his nails. This was said by some scholars if there is length in them. If he takes them in his house, that suffices. And if he is going to offer a sacrifice, he should not take anything. If he is going to offer a sacrifice and enter the state of ihram in the ten days of Dhul-Hijjah, he should not take anything from his mustache, armpits, private parts, or nails.
As for the statement: this is a hadith, but it does not contain “or a sacrifice is offered on his behalf.” Its wording is that the Prophet (peace and blessings be upon him) said: And in the other wording: It does not contain “or a sacrifice is offered on his behalf.” This is an addition from the words of some jurists or scholars. So the one who offers a sacrifice is the one who does not take anything if he intends to offer a sacrifice; he does not take from his hair, nails, or skin anything until he offers the sacrifice.
As for the one for whom a sacrifice is offered, such as his wife and children, there is no harm in them taking; there is no blame on them for taking. Because the one who offers the sacrifice is the head of the household who spent the money; this is the correct view. He should be patient until the second day, but his shortening of hair for 'Umrah from his head, and his shaving in Hajj, does not fall under this. That is, if he circumambulates and performs sa'y, he shortens, and this is not included in the prohibition. And if he throws the stones on the day of the festival and shaves, it is not included in the prohibition. But he should not take anything from his mustache, nails, armpits, or private parts.
