Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "Keeping horses may be a source of reward to some (man), a shelter to another (i.e. means of earning one's living), or a burden to a third. He to whom the horse will be a source of reward is the one who keeps it in Allah's Cause (prepare it for holy battles) and ties it by a long rope in a pasture (or a garden). He will get a reward equal to what its long rope allows it to eat in the pasture or the garden, and if that horse breaks its rope and crosses one or two hills, then all its footsteps and its dung will be counted as good deeds for its owner; and if it passes by a river and drinks from it, then that will also be regarded as a good deed for its owner even if he has had no intention of watering it then. Horses are a shelter from poverty to the second person who keeps horses for earning his living so as not to ask others, and at the same time he gives Allah's right (i.e. rak`at) (from the wealth he earns through using them in trading etc.,) and does not overburden them. He who keeps horses just out of pride and for showing off and as a means of harming the Muslims, his horses will be a source of sins to him." When Allah's Messenger (ﷺ) was asked about donkeys, he replied, "Nothing particular was revealed to me regarding them except the general unique verse which is applicable to everything: "Whoever does goodness equal to the weight of an atom (or small ant) shall see it (its reward) on the Day of Resurrection."

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, " Horses are kept for one of three purposes; for some people they are a source of reward, for some others they are a means of shelter and for some others they are a source of sins. The one for whom they are a source of reward, is he who keeps a horse for Allah's Cause (i.e. Jihad) tying it with a long tether on a meadow or in a garden with the result that whatever it eats from the area of the meadow or the garden where it is tied will be counted as good deeds for his benefit, and if it should break its rope and jump over one or two hillocks then all its dung and its foot marks will be written as good deeds for him; and if it passes by a river and drinks water from it even though he had no intention of watering it, even then he will get the reward for its drinking. As for the man for whom horses are a source of sins, he is the one who keeps a horse for the sake of pride and pretense and showing enmity for Muslims: such a horse will be a source of sins for him. When Allah's Messenger (ﷺ) was asked about donkeys, he replied, "Nothing has been revealed to me about them except this unique, comprehensive Verse: "Then anyone who does an atom's (or a small ant's) weight of good shall see it; And anyone who does an atom's (or a small ant's) weight of evil, shall see it.' (101.7-8)

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "Horses may be used for three purposes: For a man they may be a source of reward (in the Hereafter); for another, a means of protection; and for another, a source of sin. The man for whom they are a source of reward, is the one who keeps them for Allah's Cause and ties them with long ropes and lets them graze in a pasture or garden. Whatever those long ropes allow them to eat of that pasture or garden, will be written as good deeds for him and if they break their ropes and run one or two rounds, then all their footsteps and dung will be written as good deeds for him, and if they pass a river and drink from it though he has had no intention of watering them, even then, that will be written as good deeds for him. So such horses are a source of reward for that man. For the man who keeps horses for his livelihood in order not to ask others for help or beg his bread, and at the same time he does not forget Allah's right of what he earns through them and of their backs (that he presents it to be used in Allah's Cause), such horses are a shelter for him (from poverty). For the man who keeps them just out of pride and for showing off, they are a source of sin." Then Allah's Messenger (ﷺ) was asked about donkeys. He said, "Allah has not revealed anything to me regarding them except this comprehensive Verse: "Then anyone who has done good, equal to the weight of an atom (or a small ant) shall see it, and any one who has done evil, equal to the weight of an atom (or a small ant) shall see it." (99.7-8)

Narrated Abu Huraira:

The Prophet (ﷺ) said, "A horse may be kept for one of three purposes: for a man it may be a source of reward; for another it may be a means of living; and for a third it may be a burden (a source of committing sins). As for the one for whom it is a source of reward, he is the one who keeps his horse for the sake of Jihad in Allah's Cause; he ties it with a long rope on a pasture or in a garden. So whatever its rope allows it to eat, will be regarded as good rewardable deeds (for its owner). And if it breaks off its rope and jumps over one or two hillocks, even its dung will be considered amongst his good deeds. And if it passes by a river and drinks water from it, that will be considered as good deeds for his benefit) even if he has had no intention of watering it. A horse is a shelter for the one who keeps it so that he may earn his living honestly and takes it as a refuge to keep him from following illegal ways (of gaining money), and does not forget the rights of Allah (i.e. paying the Zakat and allowing others to use it for Allah's Sake). But a horse is a burden (and a source of committing sins for him who keeps it out of pride and pretense and with the intention of harming the Muslims." The Prophet (ﷺ) was asked about donkeys. He replied, "Nothing has been revealed to be concerning them except this comprehensive Verse (which covers everything) :--'Then whosoever has done good equal to the weight of an atom (or a small ant), Shall see it (its reward) And whosoever has done evil equal to the weight of an atom (or a small ) ant), Shall see it (Its punishment)."
