Abu Mas'ud (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him), and then he mentioned the complete hadith, in which he also said: "He (peace and blessings be upon him) offered the morning prayer in the darkness, then one day he offered it when it had become fully light, and then he never again offered it in the light until Allah Almighty took his (peace and blessings be upon him) soul."
