Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Allah, the Mighty and Majestic, says: When I take away the two dear things (the eyes) of My servant, and he is patient and hopes for the reward, I am not pleased with any reward for him less than Paradise."
