مناسك حج - مكارم شيرازى، ناصر - الصفحة ٨٧ - Acts that are Haraam in the State of Ihram
Article ١٤٥- Muhrim cannot remove hair from the body of another person, even if that person is in the state of Ihram or not, and even if it is performed by razor or scissor or any other instrument( but it has no atonement ), therefore people cannot shave others heads or faces in Mena when they are exiting from the state of Ihram, but they should exit from the state of Ihram first and then perform that act.
١٣- Performing Marriage
Article ١٤٦- Performing marriage is not permitted for Muhrim in the state of Ihram, even if he recites the marriage statement or deputize another person to do that, even if marriage performs permanently or temporarily, and marriage is invalidated in this way, and if he knows about the prohibition of that and performs marriage, then that women will be Haraam for him forever.
Also, it is not permitted that a Muhrim recites the statement of marriage for another person, even if that person is in the state of Ihram or not and in this way marriage of that person is also invalidated, but that woman does not become Haraam forever, and in none of these cases, the atonement is obligatory.
