Musnad Ahmad 1153:1695

Waki’ narrated to us, he said: Hisham narrated to us, from his father, from ‘Aisha, who said: Hind came to the Prophet, may Allah bless him and grant him peace, and said: "O Messenger of Allah, Abu Sufyan is a stingy man, and he does not give me and my children what suffices me, except for what I take from his wealth while he does not know." He said: "Take what suffices you and your children according to what is customary."
