What is the ruling on a wife seeking divorce from her husband who is afflicted with a contagious and fatal disease like AIDS, and would they be sinning if they remained together, or is that obligatory upon them?

A wife may request a divorce if she is harmed by remaining with her husband, and this includes him contracting AIDS, because it poses a great harm to her. She has the right to annul the marriage if her husband's infection with AIDS is confirmed. She may also waive this right and remain married to him. Neither spouse commits a sin if the healthy one prefers to remain with the infected one. In this case, it is preferable to strive to avoid procreation.
