There is no such thing as sins in Paradise. No one who enters Paradise will ever leave it. Allah says:
And as for those who were [destined to be] prosperous, they will be in Paradise, abiding therein as long as the heavens and the earth endure, except what your Lord should will - a bestowal uninterrupted. (11:108)
No fatigue will touch them therein, nor from it will they [ever] be removed. (15:48)
Let alone a wife and husband who love each other, even those who fought wars against each other in this world will not argue or have disputes in Paradise. Imagining a dispute in Paradise is thus absurd. The question of whether a wife will dispute with her husband is similarly absurd.
And We will have removed whatever is within their breasts of resentment, [while] flowing beneath them are rivers. And they will say, "Praise to Allah, who has guided us to this; and we would never have been guided if Allah had not guided us. Certainly the messengers of our Lord had come with the truth." And they will be called, "This is Paradise, which you have been made to inherit for what you used to do." (7:43)
And We will remove whatever is in their breasts of resentment, [so they will be] brothers, on thrones facing each other. (15:48)
No ill speech will they hear therein or any falsehood. (78:35)
