Abu Bakr bin Abu Musa narrates from his father that a questioner came to the service of the Prophet Muhammad (peace and blessings be upon him) and asked about the timings of the prayers. The Prophet (peace and blessings be upon him) did not give him any answer. Then the Prophet (peace and blessings be upon him) ordered Bilal, so he led the prayer of ‘Isha at the time of the setting of the twilight. Then, on the next day, the Prophet (peace and blessings be upon him) performed the ‘Isha prayer at one-third of the night. Then he said, "Where is the one who asked about the timings?" (The time for ‘Isha) is between these two (specified) times.
