Response: The Muhrim (one in state of ihraam) must be aware of nine things which the scholars have mentioned and these are:
1. Cutting (any) hair;
2. Cutting/trimming the nails;
3. Applying perfume;
4. Wearing (any) stitched garment;
5. Covering the head;
6. Hunting game;
7. Sexual intercourse;
8. Entering into the contract of Nikaah;
9. Touching one’s wife sexually.
All of these are impermissible for the Muhrim until he comes out of the first state of ihraam (during Hajj), whereby all of these are permissible except sexual intercourse. So, when he comes out of the second state of ihraam, sexual intercourse becomes permissible.
