Chapter: It is permissible for a Muhrim to treat his eyes

We went with Aban b. Uthman (in a state of lhram). When we were at Malal the eyes of Umar b. Ubaidullah became sore and, when we reached Rauba' the pain grew intense. He (Nubaib b. Wahb) sent (one) to Aban b. Uthman to ask him (what to do). He sent him (the message) to apply aloes to them, for 'Uthman (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) applied aloes to the person whose eyes were sore and he was in the state of Ihram.

Nubaih b Wahb reported that the eyes of Umar b. Ubaidnllah b. Ma'mar were swollen, and he decided to use antimony. Aban b. 'Uthman forbade him to do so and commanded him to apply aloes on them, and reported on the authority of 'Uthman b. Affan that the Messenger of Allah (ﷺ) had done that.
