Malik related to me from Yahya ibn Said from Said ibn al-Musayyab that Umar ibn al-Khattab said while he was leaning his back against the Kaba, "Whoever takes a stray is astray."
Muwatta Malik Book 36, Hadith 68
← Previous Hadith Malik related to me from Yahya ibn Said from Sulayman ibn Yasar that Thabit ibn ad-Dahhak al-Ansari told him that he had found a camel at Harra, so he hobbled it and mentioned it to Umar ibn al-Khattab and Umar ordered him to make it known three times. Thabit said to him, "That would distract me from the running of my estate." Umar said to him, "Then let it go where you found it."

Muwatta Malik Book 36, Hadith 67 Next Hadith → Malik related to me that he heard Ibn Shihab say, "The stray camels in the time of Umar ibn al-Khattab were numerous and left alone. No one touched them until the time of Uthman ibn Affan. He ordered that they be publicised and then sold, and if the owner came afterwards, he was given their price."
