A muhrim cutting the mustache or other hair of a non-muhrim

Hazrat Khaseef narrates that I trimmed the moustache hair of Muhammad bin Marwan while in the state of Ihram. Then I asked Hazrat Saeed bin Jubair about it; he instructed me to give one dirham in charity.

Hazrat Mujahid was asked: If a person in the state of Ihram during the month of Muharram trims the moustache hair of a person who is not in Ihram, what should he do? He replied: He should give one dirham in charity.

Hasan disliked cutting the hair and nails of a non-mahram while in the state of ihram.

Hazrat Amr bin Dinar says that one of our predecessors shortened (the prayer) in the state of Ihram with Jabir bin Zaid, and he (Jabir bin Zaid) ended his Ihram.

It is narrated from Hazrat Ikrimah that a woman in the state of Ihram may comb the hair of another lawful woman and may kill her lice.
