Things that are forbidden in ihraam are things that a person is not allowed to do because of ihraam. They are:
1 – Shaving the hair of one’s head, because Allaah says (interpretation of the meaning): “and do not shave your heads until the Hady reaches the place of sacrifice” [al-Baqarah 2:196]. The scholars included with shaving the hair on the head shaving hair on all other parts of the body, and they also included clipping or cutting the nails.
2 – Using perfume after entering ihraam – on the clothes or body, or in one’s food. Using perfume is haraam when in ihraam, because the Prophet SAWS (peace and blessings of Allaah be upon him) said concerning the man whose camel broke his neck: “Wash him with water and lotus leaves, and shroud him in his two garments, but do not cover his head or put hanoot on him.” Agreed upon.
Hanoot is a mixture of perfumes that is applied to the deceased.
3 – Intercourse, because Allaah says (interpretation of the meaning): “So whosoever intends to perform Hajj therein (by assuming Ihraam), then he should not have sexual relations (with his wife), nor commit sin, nor dispute unjustly during the Hajj” al-Baqarah 2:197].
4 – Touching with desire, because that comes under the general meaning of the verse “then he should not have sexual relations (with his wife)” and because it is not permissible for the pilgrim to get married or propose marriage, so it is more apt that it is not permissible for him to touch with desire.
5 – Getting married or proposing marriage, because the Prophet SAWS (peace and blessings of Allaah be upon him) said: “The pilgrim in ihraam should not get married, have a marriage arranged for him or propose marriage.” Narrated by Muslim.
7 – A prohibition which applies exclusively to men is wearing shirts, hooded robes, trousers, turbans and leather slippers, because the Prophet SAWS (peace and blessings of Allaah be upon him) was asked about what the muhrim should wear. He said: “He should not wear a shirt, hooded robe (burnous), trousers, a turban or leather slippers.” But he (peace and blessings of Allaah be upon him) made an exception for one who cannot find an izaar (lower garment or waist wrapper), who may wear trousers, and one who cannot find sandals, who may wear leather slippers.
8 – One of the prohibitions of ihraam that applies only to women is niqaab refers to a veil that covers the face and leaves the eyes uncovered, because the Prophet (peace and blessings of Allaah be upon him) forbade that. A similar prohibition applies to the burqa’. When a woman enters ihraam, she should not wear a niqaab or burqa’. It is prescribed for her to leave her face uncovered except when a non-mahram man passes by her, when she must cover her face and it does not matter if this cover touches her face.
