It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty says: When I take back the two most beloved and precious things of one of My servants (that is, his two eyes), I am not pleased with any reward for him less than Paradise." (Sayyiduna Anas (may Allah be pleased with him) said:) I said: O Messenger of Allah! Will he receive this same reward even if it is only one eye? He (peace and blessings be upon him) said: "Yes, even if it is only one eye (this great reward is still his)."
Al-Bukhari recorded it from Sayyiduna Anas (may Allah be pleased with him) through another route, but the words "even if it is only one eye" and everything after them are not in it; this addition is munkar (severely weak), and moreover the narrator in its chain, Sa'id bin Sulaym, is weak.
