Six things become prohibited for a Muhrim. Of these, 4 are about both men and women and 2 relate only to men.
1. Having sex with one’s spouse and everything related to it to the extent of even talk about it.
2. Hunting the terrestrial animals or even guiding towards the prey.
3. Getting a haircut or cutting nails.
4. Using perfume/fragrance of any kind.
These 4 things are prohibited for both men and women. The following 2 are only for men:
1. To wear sewn clothes.
2. To cover the head and the face.
If any of the above is done in Ihram, then as per the rules given next, Kaffara (expiation) and/or Sadqa (charity) will become Wajib.
In the first case, if someone has sex with the spouse or engages in kissing/fondling, then Dam (sacrifice of a goat or such animal) becomes Wajib, irrespective of whether ejaculation has occurred or not.
In case of hunting, whatever price 2 just Muslims decide for the prey should be given in charity. This is also Wajib.
If hair are removed from any part of the body (including the head) or from the whole body in 1 sitting, then 1 Dam becomes Wajib. If hair are removed in separate sittings, then separate Dam becomes Wajib i.e. as many Dam as the sittings.
If the hair of the head, beard, neck, armpits and private parts are removed then Dam becomes Wajib and if the hair from other parts of the body are removed then 1 Sadqa Fitr becomes Wajb.
If in Ihram all the nails of the hands and feet are cut or all the nails of 1 hand or 1 foot are cut, then Dam becomes Wajib. If less than 5 nails are cut, then for every nail half a “Sa’a” i.e. almost 1.25 kg of wheat or its price is to be given in charity. If the nail is broken in such a manner that it will not grow anymore, then there is no problem in removing it. (Fatawa A’alamgiri, Vol. 1, Pg No: 244)
