Lady Aisha (may Allah be pleased with her) says: In the time of ignorance, there were four types of marriage (after this she mentioned the hadith as previously narrated). In one narration, these additional words are present: (The husband would say to his wife) Send a message to such-and-such man, then have intercourse with him. During this period, the woman's husband would stay away from her and would not have intercourse with her until it became apparent that she was pregnant by the man with whom she had intercourse. When the woman's pregnancy became apparent, the husband would then have intercourse with her if he wished. He did this so that his offspring would be noble. This type of marriage was called Nikah Istibda’. The same narration is also transmitted with another chain, however, in it these words are present: (The husband says to his wife) Send a message to such-and-such man and become pregnant by him. The woman's husband would stay away from her and would not have intercourse with her until it became apparent that she was pregnant by the other man. This marriage was called Nikah Istirda’. Muhammad bin Ishaq states: This is correct (and in it these words are also present): When Allah Almighty sent Muhammad (peace be upon him) with the truth, He abolished the (various forms of) marriage of the time of ignorance.
