The Shaykh: Yes.

The questioner : Regarding trimming the nails and shaving hair other than the head, it is well known that these are among the prohibitions of ihram. What is the evidence for this?

The Shaykh : What is the evidence that it is not permissible to shave the hair of one's head while in a state of ihram?

The questioner : Not just the hair of the head, but his hair in general, and trimming the nails?

The Shaykh : What do you mean by "other than the hair of the head"?

The questioner : I mean, for example, some of the beard, or any hair, such as under the armpits, or plucking the pubic hair, other than the head?

The Shaykh : What is the evidence that a person in ihram is not allowed to remove hair other than from his head or trim his nails? I do not have an answer at hand right now.

The questioner : And even in the major books of fiqh...

Another questioner : And there is no general evidence; the general evidence is not even mentioned.
