Musnad Ahmad 1153:168

Narrated to us Abd al-Razzaq, who said: Informed us Sufyan, from al-A’mash, from Shaqiq, from Masruq, from Aisha, from the Prophet, peace and blessings of Allah be upon him, who said: "If a woman spends from the food of her husband"—and he mentioned its meaning, and he said: "Neither of them diminishes anything from the other."
