The Book of Lost Property

Zayd ibn Khālid al-Juhani (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) was asked about the lost and picked up item that is made of gold or silver, whereupon he said: "Remember the description of its container and the string with which it is tied. Make a public announcement of it for one year. If nobody comes and claims it, then utilize the money but keep it as a trust with you. If its owner comes back one day seeking it, then return it to him." Then, he asked him about the lost camel, whereupon the Prophet (may Allah's peace and blessings be upon him) said: "It is none of your concern. Leave it, for it has its feet and a water container (reservoir), and it will reach water and eat from the trees until its owner finds it." He then asked him about the lost sheep, whereupon he said: "Take it, for it is either for you, or for your brother, or for the wolf."

Abu Shurayh Khuwaylid ibn ‘Amr al-Khuzā‘i reported that the Prophet (may Allah's peace and blessings be upon him) said: "Whoever believes in Allah and the Last Day let him honor his guest with his due reward." They said: "O Messenger of Allah, what is his due reward?" He said: "A day and a night (of excellent accommodation), and hospitality is for three days, and whatever is beyond that is charity offered to him." In another version: "It is not lawful for a guest to stay (for long) at the home of his brother to the point that he causes him to sin." They said: "O Messenger of Allah, how does he cause him to sin?" He said: "He overstays with him till he has nothing to serve to him."

Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: While we were on a journey with the Messenger of Allah (may Allah's peace and blessings be upon him) a man came while riding a mount of his, and he began to look on the right and left. The Messenger of Allah (may Allah's peace and blessings be upon him) said: "The one who has an extra mount should hand it over to one who has no mount, and the one who possesses surplus provision should give it to the one who has no provision." He named various kinds of properties until we began to think that none of us had any right to anything surplus.
