It is narrated from Ibn Shihab that Sayyiduna Umar bin Khattab (may Allah be pleased with him) ordered the killing of snakes in the Haram.

Imam Malik (may Allah have mercy on him) said that by the biting dog, which has been ordered to be killed in the Haram, is meant any animal that bites people or attacks them, or frightens them, such as a lion, leopard, bear, and wolf; it is permissible to kill such an animal, and it is included among biting dogs. However, those beasts that do not attack, such as the badger, fox, and cat, and those similar to them, the muhrim should not kill them; if he does, then compensation will be obligatory upon him. Imam Malik (may Allah have mercy on him) said: The muhrim should not kill those beasts that cause harm, except those which the Messenger of Allah (peace and blessings be upon him) has named, the crow and the kite; if the muhrim kills any bird other than these two, then compensation will be obligatory upon him.

Malik said regarding the vicious dog that was commanded to be killed in the Haram: Indeed, everything that attacks people, assaults them, and frightens them, such as the lion, the tiger, the leopard, and the wolf, is the vicious dog. As for those beasts that do not attack, like the hyena, the fox, the cat, and those similar to them among the beasts, the muhrim does not kill them. If he kills one, he must pay a penalty.

As for that which is harmful among the birds, the muhrim does not kill it except for what the Prophet, peace and blessings be upon him, named: the crow and the kite. And if the muhrim kills anything among the birds other than these two, he must offer a ransom.

It is narrated from Rabi'ah bin Abdullah that he saw Sayyiduna Umar bin Khattab (may Allah be pleased with him) removing lice from his camel and throwing the lice into the dust at the place of Suqya, and he was in the state of Ihram.

Imam Malik (may Allah have mercy on him) said: I consider this act to be disliked.

Hazrat Marjana heard from Umm al-Mu'mineen Sayyida Aisha Siddiqa (may Allah be pleased with her). She was asked whether a muhrim (person in the state of ihram) may scratch his body. She replied: Yes, he may scratch, and he may scratch vigorously, and if my hands were tied and my feet were restrained, I would scratch with that as well.

It is narrated from Ayub bin Musa that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) looked into a mirror because of an illness that was in his eye, and he was in the state of Ihram.

It is narrated from Nafi‘ that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) considered it disliked to remove lice or nits from his camel.
Imam Malik (may Allah have mercy on him) said: I like this statement which I have heard regarding this matter.

Muhammad bin Abdullah bin Abi Maryam asked Sa'id bin al-Musayyib that one of my nails has broken and I am in the state of Ihram. Sa'id said: Cut it off.

Imam Malik, may Allah have mercy on him, was asked: If a person in the state of ihram has pain in his ear, can he put oil of ban (wild olive) without fragrance in his ear? He replied: There is no harm in it, and if he puts it in his mouth, there is also no harm.

Imam Malik, may Allah have mercy on him, said: If a person in the state of ihram lances his boil, bursts a blister, or opens a vein for bloodletting out of necessity, then there is no harm in it.
