It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Allah Almighty says: 'When I take away the sight of both eyes of My servant, I am not pleased with any reward for him less than Paradise.'" The narrator says: I said: "O Messenger of Allah, and if it is one (eye whose sight has gone, will this reward also be attained)?" The Prophet (peace and blessings be upon him) said: "Even if it is one (the same reward will be attained)." (Allamah Haythami says:) I say: This hadith is in the Sahih, except that it does not contain the words: "Even if it is one."
Abu Ya'la recorded it. Its chain contains a narrator, Sa'id bin Sulaym al-Dabbi, whom al-Azdi declared da'if (weak). Ibn Hibban mentioned him in his book al-Thiqat and said: "He makes mistakes."
