Nubayh ibn Wahb reported that Umar ibn Ubaydullah ibn Ma’mar had eye trouble while he was a muhrjm. He asked Aban ibn Uthman who said, “Give them a dressin with aloes. For, I had heard Uthman ibn Affan mention that Allah’s Messenger (SAW) said : Dress that with aloes.”
[Muslim 1204, Abu Dawud 1838, Nisai 2707]
