Section : Leaving Makkah Before the 8th of Zhul-Hijjah.
Sa’id bin Mansur reported that Al-Hasan used to leave Makkah for Mina a day or two before Yaum al-Tarwiya (on the 6th or 7th of Zhul-Hijjah). Malik, however, disliked it, and also disliked that one should stay in Makkah until the evening of Yaum al-Tarwiya, except when it is Friday and one is still in Makkah and it is time for the Friday prayer. In such a case one must offer Friday prayer before leaving for Mina.
