Arousing The Intellects, The Book of At-tahaarah

Those who write in fiqh and the ahaadeth of the legal rulings began their books with at-tahaarah because it is the key to the prayer which is the most significant of the pillars of Islaam after ash-shahaadatain, bearing witness that there is no deity that has the right to be worshipped except Allah and that Muhammad is the Messenger of Allah. So there is no prayer without purification.
