Habib bin Abi Thabit narrated that we were with Abdullah bin Umar (may Allah be pleased with them) when a Bedouin came and said: "I have given one of my sons a she-camel for as long as he lives." Amr said in the narration: "And it bore many offspring," and Ibn Abi Najih said in his narration: "Rather, it had many offspring and they became restless." Ibn Umar (may Allah be pleased with them) said: "The she-camel belongs to him, whether it lives or dies." The man said: "But I had given it to him as charity." He replied: "Then you cannot take it back under any circumstance."
