Yahya related to me from Yahya ibn Said from Muhammad ibn Ibrahim ibn alHarith at-Taymi from Rabia ibn Abi Abdullah ibn alHudayr that he saw Umar ibn al-Khattab taking the ticks off a camel of his at as- Suqya while he was in ihram .

Malik said that he disapproved of that.
Muwatta Malik Book 20, Hadith 94
← Previous Hadith Yahya related to me from Malik from Ibn Shihab that Umar ibn al- Khattab told people to kill snakes in the Haram.

Malik said, about the "wild dogs" which people were told to kill in the Haram, that any animals that wounded, attacked, or terrorised men, such as lions, leopards, Iynxes and wolves, were counted as"wild dogs." However, someone who was in ihram should not kill beasts of prey that did not attack (people), such as hyenas, foxes, cats and anything else like them, and if he did then he had to pay a forfeit for it. Similarly, someone in ihram should not kill any predatory birds except the kinds that the Prophet, may Allah bless him and grant him peace, specified, namely crows and kites. If someone in ihram killed any other kind of bird he had to pay a forfeit for it.

Muwatta Malik Book 20, Hadith 93 Next Hadith → Yahya related to me from Malik from Alqama ibn Abi Alqama that his mother said, "I heard A'isha, the wife of the Prophet, may Allah bless him and grant him peace, being asked whether some one in ihram could scratch their body or not, and she said, 'Yes, he can scratch it and do so as hard as he pleases. I would scratch even if my hands were tied and I could only use my feet.' "
