And otherwise, she takes the full dowry, a separation between them occurs, and she must observe the waiting period ('Idda) (1). This is because the surrender (Taslim) that was due from her has been fulfilled, and the menstruation, the state of Ihram, or the vaginal blockage (Rataq) are factors not stemming from her side, so they do not affect the dowry, just as they do not affect the cancellation of financial support (Nafaqa). It has also been narrated that the dowry is not completed by this (2), which is the opinion of Shurayh and Abu Thawr, because he was not able to take possession of her, and thus she was not entitled to a dowry [by preventing him] (4), just as if she prevented the surrender of herself to him. This is confirmed by the fact that there is no difference whether the obstacle to surrender is from a third party or the contracting party, as is the case in a lease agreement (Ijara). From Ahmad, there is a third report: if both were fasting the fast of Ramadan, the dowry is not completed, and if it was other than that, it is completed. Abu Dawud said: I heard Ahmad being asked about a man who entered upon his wife, while both were fasting outside of Ramadan, and he locked the door and let down the curtain? He said: The dowry has become mandatory. It was said to Ahmad: And the month of Ramadan? He said: The month of Ramadan is different from this. It was said to him: And what if he were a traveler in Ramadan? He said: This one is a person who has broken the fast. Meaning: the dowry has become mandatory. This indicates that whenever the obstacle is confirmed, such as Ihram and the fast of Ramadan, the dowry is not completed. The Qadi said: If the obstacle does not prevent the incentives for intercourse, such as castration (Jabb), impotence ('Unna), vaginal blockage (Rataq), illness, menstruation, and postpartum bleeding (Nifas), the dowry is mandatory. If it prevents the incentives, such as Ihram and the obligatory fast, then there are two reports. Abu Hanifa said: If the obstacle is from her side, the dowry is not established; if it is from his side, such as an obligatory fast or Ihram, the dowry is also not established (5). But if it is castration or impotence, the dowry is completed, because the obstacle is from his side, and that does not prevent the existence of the surrender due from her, so her right is completed, just as a minor is obligated to pay the maintenance of his wife if she surrenders herself to him.
