Narrated Jabir: Bashirs wife said (to her husband): Give my son your slave, and call the Messenger of Allah ﷺ as witness for me. So he came to the Messenger of Allah ﷺ and said: The daughter of so-and-so has asked me to give her som my slave and said to me: Call the Messenger of Allah ﷺ as witness for her. He asked: Has he brothers? He replied: Yes. He again asked: Has he given them all the same as you have given him? He replied: No. He said: This is not good, and I will be a witness to what it right.
