Am I obligated to wear the niqab at my husband's request, even though I do not prefer wearing it?

The difficulty in wearing the niqab will disappear with habituation, and it is not permissible to abandon it for this reason. The niqab is obligatory if the husband commands it, and if the husband does not obligate her, it is advisable to fulfill his wish, seeking Allah's reward for obedience and enduring patiently until the difficulty ceases.
