Recognise well the strap and the bag (containing) that and then make an announcement regarding that for one year, but if none recognises it, then spend that and it would be a trust with you; and if someone comes one day to make demand of that, then pay that to him. He (the inquirer) asked about the lost camel, whereupon he said: You have nothing to do with that. Leave that alone, for it has feet and also a leather bag, it drinks water, and eats (the leaves) of the trees. He asked him about sheep, whereupon he said: Take it, it is for you, or for your brother, or for the wolf.
Sahih Muslim Book 31, Hadith 5
The Prophet (ﷺ) did not take omens from anything, but when he sent out an agent he asked about his name. If it pleased him, he was glad about it, and his cheerfulness on that account was visible in his face. If he disliked his name, his displeasure on that account was visible in his face. When he entered a village, he asked about its name, and if it pleased him, he was glad about it, and his cheerfulness on that account was visible in his face. But if he disliked its name, his displeasure on that account was visible in his face.
Sunan Abi Dawud Book 30, Hadith 17
