What is the ruling of Islamic law regarding the difficulty in completing conjugal relations with the wife and the husband's inability to achieve full penetration, and what if the wife requests Khulʿ? Is she entitled to the deferred Mahr, even though the husband is the one who supports the child? Is it permissible for the wife to refuse to visit the husband's family if she hears his brothers speak ill of her, knowing that it is obligatory for her to visit them?

A woman has the right to request a khulʿ (divorce at the wife's instance) from her husband if she dislikes him and cohabitation becomes impossible, in exchange for money she offers to free herself, as Allah Almighty said: ﴿فَإِنْ خِفْتُمْ أَلَّا يُقِيمَا حُدُودَ اللَّهِ فَلَا جُنَاحَ عَلَيْهِمَا فِيمَا افْتَدَتْ بِهِ﴾ (But if you fear that they will not uphold the limits of Allah, then there is no blame upon them for what she gives to free herself), and as occurred with the wife of Thabit ibn Qays. A wife’s request for khulʿ – especially if the husband is unable to fulfill her right to conjugal relations – is a legitimate right, and it is commendable for the husband to respond to it. None of the marital rights, such as maintenance (nafaqa) and deferred dower (mu'akhkhar as-sadaq), are forfeited due to khulʿ, unless the deferred dower was part of what she offered to free herself. The wife is not obligated to live with the husband's parents or siblings; rather, she has the right to demand her own separate dwelling.
