What is the evidence for those who consider cutting the nails of a person in ihram to be among the prohibitions of ihram?

Shuqara: Our Shaykh, may Allah bless you, two or three hours ago one of the brothers visited me and asked a question, which was: There is no god but Allah, there is no god but You, Glorified are You... Ah, cutting the nails in Hajj is among the prohibitions of Hajj.

The Shaykh: Yes.

The questioner : So, is there evidence for this? The truth is, I was present and I told him that it is well known that cutting the nails or the fingernails in Hajj is a matter of luxury, and this is, of course, among the prohibitions, or rather, the wisdom or part of the wisdom of Hajj is not realized by it. Then, there is perhaps another evidence, or a general textual evidence in this specific issue, which is that the Prophet (peace and blessings be upon him) said: , and this is, of course, intended so that one sacrifices, as came in the hadith, that the ruling intends for one to imitate or follow those pilgrims who perform their Hajj and its rites in the rituals of Hajj. I mentioned this, and he said: I also wanted to ask whether this is suitable as evidence or not.

The Shaykh : By Allah, I was also asked this question, and my answer was very brief: that I have no answer at hand, yes, and that the matter is delicate and requires review. As for what you mentioned regarding cutting the nails being a matter of luxury, and the pilgrim not being so, this does not, in my opinion, stand as evidence for the prohibition of cutting the nails for the pilgrim. That is because we have in the authentic Sunnah what permits the person in ihram to take a bath, as it is said today, and there is no doubt that in this bathing there is something of luxury, especially if the weather is hot and the water is cold, so he undoubtedly finds some comfort. Therefore, comfort does not contradict Hajj. Rather, we worship by what Allah has commanded us, or we draw near to Him by abstaining from what Allah has forbidden. And as you know, expanding the scope of restriction and prohibition on people through analogical reasoning is a matter that involves some roughness and difficulty.
