It is narrated from Sayyiduna Abu Wahb Jashmi, may Allah be pleased with him, who had the honor of companionship, that the Messenger of Allah, peace and blessings be upon him, said: Name yourselves after the names of the noble Prophets. The most beloved names to Allah Almighty are Abdullah and Abdur Rahman. The truest names are Harith and Hammam, and the most unpleasant names are Harb and Murrah. Keep horses ready for the protection of the borders, touch their foreheads and hindquarters, and put collars on them, but they should not be made of hemp. Take care of these types of horses: those with a blackish-red, that is, crimson color, with whiteness on their foreheads and legs; a white and red horse with whiteness on its forehead and legs; and a very black horse with whiteness on its forehead and legs.
