Musannaf Ibn Abi Shayba 35:18

'Abbad narrated to us, from Husayn, from al-Sha'bi, who said: I heard al-Nu'man ibn Bashir saying: My father gave me a gift, so my mother, 'Amrah bint Rawahah, said: "I will not be satisfied until you have the Prophet, peace and blessings of Allah be upon him, bear witness to it." He said: So he came to the Prophet, peace and blessings of Allah be upon him, and said: "I gave my son from 'Amrah a gift, and she ordered me to have you bear witness to it." He said: "Did you give all of your children the like of this?" He said: "No." He said: "Then fear Allah and act justly between your children."
