A man came to Allah's Messenger (ﷺ) and asked about Al-Luqata (a fallen thing). The Prophet (ﷺ) said, "Recognize its container and its tying material and then make a public announcement about it for one year and if its owner shows up, give it to him; otherwise use it as you like." The man said, "What about a lost sheep?" The Prophet (ﷺ) said, "It is for you, your brother or the wolf." The man said "What about a lost camel?" The Prophet (ﷺ) said, "Why should you take it as it has got its water-container (its stomach) and its hooves and it can reach the places of water and can eat the trees till its owner finds it?"
Sahih al-Bukhari Book 42, Hadith 20
← Previous Hadith 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."

Sahih al-Bukhari Book 42, Hadith 19 Next Hadith → The Prophet (ﷺ) said, "No doubt, one had better take a rope (and cut) and tie a bundle of wood and sell it whereby Allah will keep his face away (from Hell-fire) rather than ask others who may give him or not."
