Ибн Таймия
The second invasion lasted between October 1300 and January 1301. Ibn Taymiyyah at this time began giving sermons on jihad at the Umayyad mosque. Ibn Taymiyyah also spoke to and encouraged the Governor of Damascus, al-Afram, to achieve victory over the Mongols. He became involved with al-Afram once more, when he was sent to get reinforcements from Cairo.
