Sayyiduna al-Irbad bin Sariyah (may Allah be pleased with him) narrated it as a saying of the Prophet (marfu'an): Allah, the Mighty and Majestic, said: "When I take from My servant his two precious things (his eyes) and he grieves over losing them, I am not pleased with any reward for him less than Paradise."
