Alqamah narrated that :Ibn Mas'ud was asked about a man who married a woman and he did not stipulate the dowry for her, and he did not enter into her until he died. So Ibn Mas'ud said: "She gets the same dowry as other women, no less and no more, she has to observe the Iddah, and she gets inheritance." So Ma'qil bin Sinan Al-Ashja'I stood and said: "The Messenger of Allah judged the same as you have judged regarding Birwa bint Washiq, a woman of ours." So Ibn Mas'ud was happy about that
