It is narrated from Abu Qays al-Awdi that a woman named Salamah was given in marriage by her mother, and the matter was brought before Sayyiduna Ali (may Allah be pleased with him). He asked: Has her husband not gone in to her? They said: Yes, he has. So he declared the marriage valid.
(b) It is narrated from Bahriyyah bint Hani bin Qabisah that she married herself to al-Qa'qa' bin Shawr and spent the night with her husband. Her father brought the matter before Sayyiduna Ali (may Allah be pleased with him), and he asked: Has her husband gone in to her? He said: Yes. So Sayyiduna Ali (may Allah be pleased with him) declared her marriage valid. This report has come with differing chains and wordings, and it hinges on Abu Qays al-Awdi, whose uprightness is disputed, and Bahriyyah is unknown (majhulah). The condition of consummation would make the marriage valid only if this mawquf report were established. Consummation cannot make the unlawful lawful; the first report from Sayyiduna Ali (may Allah be pleased with him), which stipulates the guardian, is sahih (authentic), and it is the one to be relied upon.
