Bulugh al-Maram #1200

Narrated 'Alqamah on the authority of Ibn Mas'ud (RA): He was asked about a man who had married a woman and had not fixed a dowry for her. And he did not consummate (the marriage) with her till he died. Ibn Mas'ud replied, "She should receive a dowry similar to what the women of her community receive without decrease or increase. She must observe the 'Iddah period (of waiting before re-marrying and is entitled to a share of the inheritance." Ma'qil bin Sinan al-Ashja'i then got up and said, "Allah's Messenger (ﷺ) ruled the same as your ruling regarding Birwa', daughter of Washiq, a woman of our tribe." Ibn Mas'ud was delighted with it. . Narrated Jabir bin 'Abdullah (RA): The Prophet (ﷺ) said: "If anyone gives as a dowry to a woman some flour or dates, he has made her lawful for himself." .
