Sayyidah Umm Malik al-Bahziyyah (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) mentioned a tribulation and said: "The best of you, and the best of people, in it is a man who keeps apart with his wealth, worshipping Allah and paying its due, and a man holding the reins of his horse, who strikes fear into the enemy and the enemy strikes fear into him."
