It is narrated from Alqamah (may Allah have mercy on him) that a question was brought to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) about a man who had died leaving his wife; he had not consummated the marriage with her, nor fixed a dower for her. People kept coming back to Ibn Mas'ud (may Allah be pleased with him) about it for a month, and he would say nothing. Then he said: I will give my own opinion on it; if it is wrong, it is from me, and if it is correct, it is from Allah. I say: "She will receive the dower of women like her; she must observe the waiting period ('iddah), and she will inherit." Then Ma'qil bin Yasar al-Ashja'i (may Allah be pleased with him) stood up and said: "The Messenger of Allah (peace and blessings be upon him) gave exactly the same judgement in the case of Barwa' bint Washiq as you have given." And Ibn Mas'ud (may Allah be pleased with him) was delighted.
