Abu Dawud Book 6, Hadith Number 2208.
Narated By Khuwaylah, daughter of Malik ibn Tha’labah : My husband, Aws ibn as-Samit, pronounced the words: You are like my mother. So I came to the Apostle of Allah (PBUH), complaining to him about my husband.
The Apostle of Allah (PBUH) disputed with me and said: Remain dutiful to Allah; he is your cousin.
I continued (complaining) until the Qur’anic verse came down: “Allah hath heard the words of her who disputeth with thee concerning her husband….” till the prescription of expiation.
He then said: He should set free a slave. She said: He cannot afford it. He said: He should fast for two consecutive months. She said: Apostle of Allah, he is an old man; he cannot keep fasts. He said: He should feed sixty poor people. She said: He has nothing which he may give in alms. At that moment an araq (i.e. date-basket holding fifteen or sixteen sa’s) was brought to him.
I said: I shall help him with another date-basked (‘araq). He said: You have done well. Go and feed sixty poor people on his behalf, and return to your cousin. The narrator said: An araq holds sixty sa’s of dates.
