Abu Bakr bin Abu Musa narrates from his father, Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him): A man came to the service of the Prophet Muhammad (peace be upon him) and asked him about the prayers, but he did not give him any answer. The Prophet (peace be upon him) instructed Sayyiduna Bilal (may Allah be pleased with him), so he gave the iqamah for the morning prayer when the true dawn had appeared. The Prophet (peace be upon him) performed that prayer. Then, under the command of the Prophet (peace be upon him), he gave the iqamah for the Zuhr prayer at a time when a person would think that the sun had declined or had not yet declined; however, the Prophet (peace be upon him) knew better about it. Then, under the command of the Prophet (peace be upon him), he gave the iqamah for the Asr prayer at a time when the sun was still high. Then, under the command of the Prophet (peace be upon him), he gave the iqamah for the Maghrib prayer when the sun had set. Then, under the command of the Prophet (peace be upon him), he gave the iqamah for the Isha prayer when the twilight had disappeared.

The narrator states: The next day, the Prophet (peace be upon him) performed the Fajr prayer at a time when a person would think that the sun had risen or had not yet risen; however, the Prophet (peace be upon him) knew better about it. Then, the Prophet (peace be upon him) performed the Zuhr prayer at the same time as he had performed the Asr prayer on the previous day. When he performed the Asr prayer, a person would think that the sun had turned red, meaning the sunlight had faded. Then, the Prophet (peace be upon him) performed the Maghrib prayer shortly before the twilight had disappeared. Then, he performed the Isha prayer after one third of the night had passed. Then, he asked: "Where is the person who asked the question? Between these two times is the specific time for the prayers."
