Sayyiduna Anas bin Malik (may Allah be pleased with him) says that I heard the Noble Prophet (peace and blessings of Allah be upon him) say: "Allah, the Most Great and Exalted, says: When I test My servant by taking away his two beloved things and he remains patient over it, I certainly grant him Paradise in exchange for both." (By this) the Prophet (peace be upon him) meant the eyes.
