Habib bin Abi Thabit narrated that I was with Ibn Umar (may Allah be pleased with them) when a man from among the Bedouins came and said, "I had gifted a she-camel to my son for as long as he lived, and she bore many camels." So Ibn Umar (may Allah be pleased with them) said: "That she-camel belongs to him, whether he lives or dies." The man said: "I had given it as charity." Ibn Umar (may Allah be pleased with them) said: "If that is the case, then you cannot take it back under any circumstance."

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."
