Musnad Ahmad 1167:11

Abu Mu'awiyah narrated to us, he said: Hisham ibn 'Urwah narrated to us, from Fatimah bint al-Mundhir, from Asma' bint Abi Bakr, she said: The Messenger of Allah (peace and blessings of Allah be upon him) said to me: "Give, or bestow, or spend, and do not withhold, lest Allah withhold from you. And do not count, lest Allah count against you."
