He said: "A woman shall not travel for a distance of two days or two nights, unless her husband or a mahram is with her." "And there is no fasting on two days: the day of al-Fitr and the day of al-Nahr." "And there is no prayer after two prayers: after the morning [prayer] until the sun rises, and after the afternoon [prayer] until the sun sets." "And journeys shall not be undertaken except to three mosques: the Sacred Mosque, al-Aqsa Mosque, and this mosque of mine."
