It is narrated from Sayyiduna Suhayb (may Allah be pleased with him) that he said: I came to the Messenger of Allah (peace and blessings be upon him), and before him (peace and blessings be upon him) were dates and bread. He (peace and blessings be upon him) said: "Come near and eat." So I began eating the dates, and he (peace and blessings be upon him) said: "Are you eating dates while you have an eye ailment?" I said: O Messenger of Allah, I am chewing them on the other side. And the Messenger of Allah (peace and blessings be upon him) smiled.
