Masruq (may Allah have mercy on him) said: A question was brought to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) about a man who left his wife without having consummated the marriage with her. People kept coming back to him about it for a month, and he would give no judgement. 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: "She will receive the like of the dower of women like her; she must observe the waiting period ('iddah), and she will inherit." Then Abu Sinan al-Ashja'i (may Allah be pleased with him) stood up and said: "The Messenger of Allah (peace and blessings be upon him) gave this very judgement in the case of Barwa' bint Washiq." And Abdullah bin Mas'ud (may Allah be pleased with him) was delighted by that.
