Musnad Ahmad 1167:59

Abu Bakr al-Hanafi narrated to us, he said: al-Dahhak bin Uthman narrated to me, he said: Wahb bin Kaysan narrated to me, he said: I heard Asma bint Abi Bakr, she said: The Messenger of Allah, may Allah bless him and grant him peace, passed by me while I was counting something and measuring it. He said: "O Asma, do not count, lest Allah count against you." She said: "So I did not count anything after the saying of the Messenger of Allah, may Allah bless him and grant him peace, that went out from me, nor that entered upon me. And nothing of the provision of Allah ran out with me, except that Allah, the Exalted and Majestic, replaced it."
