A worthy spouse is not of this world, but of the next"
- Abu Sulayman Ad Darani
In other words, the worthy spouse allows you to be free to engage in the work of the next world.
When you keep to your worship, if a boredom should appear such that the heart is wearied and you fall behind in worship, looking at her/him and witnessing her/his intimacy and ease to the heart.
That power of worship will return and your desire to obey God will be renewed.
(Sachiko Murata, Tao of Islam)
