Make du’a for your spouse, constantly. There is no greater support you could give each other than asking the Lord of the Worlds to help him/her in their earthly struggle. And when you have done that, ask him/her to make du’a for you too, for how beautiful is it that a couple remembers each other in their sujud, thanking and asking for guidance from the One who brought them together in the first place. Wouldn’t you love it for them to remember you in their prayers? Likewise, the opposite is true. Your spouse loves it when you remember them in front of The Most High, for you don’t love someone until you love what they love.
