Abdur Rahman bin Yazid narrates, while describing the story of the Hajj he performed with Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him): Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) led us in the Maghrib prayer at Muzdalifah. After that, he called for the evening meal, ate it, then performed the ‘Isha prayer, and then went to sleep. When the true dawn had just appeared, he got up and performed the Fajr prayer. I said: You do not usually perform the Fajr prayer this early? He used to perform the Fajr prayer after it had become light. He replied: I saw the Messenger of Allah (peace and blessings be upon him) perform the prayer at this place and on this day at this very time.
