Masruq (may Allah have mercy on him) narrates from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) concerning a man who married a woman and then died before consummating the marriage with her, without having fixed a dower for her, that he said: "She will receive the full dower; she must observe the waiting period ('iddah), and she will inherit." Then Ma'qil bin Sinan (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him): "He (peace and blessings be upon him) gave this very judgement in the case of Barwa' bint Washiq."
