Sayyiduna Abu Umamah (may Allah be pleased with him) said: I was present with the Messenger of Allah (peace and blessings be upon him) at the Farewell Hajj, and I heard him (peace and blessings be upon him) saying, and he narrated the hadith, and he also said: "Beware! It is not permissible for a woman to give anything from her husband's wealth without his permission." A man said: O Messenger of Allah, not even food? He (peace and blessings be upon him) said: "That is among the best of our wealth."
