Does consummation of marriage with one woman eliminate the husband's status as 'Aan' (impotent) regarding all other women?

If a man has sexual intercourse with a woman, his legal status as 'Aan' (incapable of consummation) is not negated with respect to other women. This is the established position. The reasoning is that the decree of impotence is specific to each woman, as evidenced by the fact that if impotence is established against him, the right of annulment held by one wife does not lapse if another wife is satisfied and accepts the situation. Furthermore, annulment is established to remove harm resulting from the inability to consummate that specific marriage, which harm does not cease by intercourse with another woman. The difference in ability may be attributed to intense love, inclination, or specific beauty concerning one woman over another.

Ibn Aqil holds that if he is proven impotent with one woman, he is considered impotent concerning all women. This is the position reported from Abu Bakr, and it aligns with those who state that testing him with another wife is sufficient. This view is also attributed to Samura and Umar ibn Abd al-Aziz, based on the premise that impotence is an innate, unchangeable physical disposition; thus, if absent for one, it must be absent for all. According to this view, if he consummates intercourse even once, his impotence is never established.
