Regarding Al-'Arafah Sunan Abi Dawud 2934
They were at a watering place from among the watering places, and when Islam reached them, the master of the water made a deal with his people for a hundred camels on condition that they embrace Islam. So they embraced Islam, and he distributed the camels among them. Then it occurred to him to take them back from them, so he sent his son to the Prophet (ﷺ) and said to him: Go to the Prophet (ﷺ) and say: My father sends his greetings to you, and he made a deal with his people for a hundred camels on condition that they embrace Islam, so they embraced Islam, and he distributed the camels among them. Then it occurred to him to take them back from them. Is he more entitled to them, or are they? If he says yes or no, then say to him: My father is an old man, and he is the chieftain of the water, and he asks you to appoint me the chieftain after him.
So he came to him and said: My father sends his greetings to you. He replied: And upon you and upon your father be peace. He said: My father made a deal with his people for a hundred camels on condition that they embrace Islam, so they embraced Islam and their Islam was sincere. Then it occurred to him to take them back from them. Is he more entitled to them, or are they? He replied: If it occurred to him to give them to them, let him give them; and if it occurred to him to take them back, he is more entitled to them than them. If they have embraced Islam, then their Islam belongs to them, and if they have not embraced Islam, they shall be fought on account of Islam.
He said: My father is an old man, and he is the chieftain of the water, and he asks you to appoint me the chieftain after him. He replied: Chieftaincy is a right, and people must have chieftains, but the chieftains are in the Fire.
