Then he was asked, „O Messenger of Allah, praise and peace be
upon him, what about horses?‟ He answered, „Horses will be divided
into three groups: those that are a burden for their owner, those that
are a shield for him and those that make their owner worthy of
reward. As for those who are a burden for their owner, they are the
ones who are bred for show or for pride, or as a cause of injury to
Muslims. They will be a cause of punishment for their owner. The
ones that are a shield for their owners are those that were bred by
him for the Cause of Allah and he does not forget that which is due
to Allah in respect of their backs and their necks. They are his
shield. These horses make their owner worthy of reward and are the
ones raised in meadows and gardens for use in the Cause of Allah
by Muslims. Whatever they eat from meadows and gardens is
recorded as good deeds of their owner, so much so that even their
droppings and urine count as an equal number of good deeds for
him. Every rope that is used (when they are being broken in), their
jumping and every mound from which they jump and every hoof
mark they make counts as an equal number of good deeds for him.
