It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him); he said: I had a complaint in my eye, and the Messenger of Allah (peace and blessings be upon him) came to visit me. He (peace and blessings be upon him) said: "O Zayd, if your eyes remain as they are, what will you do?" I said: "Then I will hope for the reward and be patient." He said: "Then you will meet Allah without any sin."
