Affection witht the partner erases bad deeds

Imām ʿAlī (a.s.) said: ,,ʿUthmān ibn Maẓʿūn (r.a.) came to the Messenger of God (s.a.) and said: “O Messenger of God.” Until he then said: “I have taken it upon myself to forbid me Khawlah.” By which he (r.a.) meant his wife. He (s.a.) said: “Do not do that, O ʿUthmān, for if the believing servant took the hand of his partner, then God wrote down for him ten good deeds and blotted out for him ten bad deeds. If he kissed her, then God wrote down for him a hundred good deeds and erased from him a hundred bad deeds. When he has intercourse with her, God wrote down for him a thousand good deeds and erased from him a thousand bad deeds and the angels entered into her presence. When the two perform ablution (ghusl), the water does not flow over a single hair of each of them except that God inscribed a good deed on them for this one and erased a bad deed from them for that one. If this took place on a cold night, then God said to the angels: “Look at these two servants of Mine who washed themselves on that cold night, knowing that I am their Lord. I will have you testify that I have forgiven them both.” If a child results from their sexual act, then it will be at their service in Paradise.” Thereafter, the Messenger of God (s.a.) tapped the chest of ʿUthmān ibn Maẓʿūn (r.a.) with his hand and said: “O ʿUthmān, do not stay away from my custom [Sunnah], for whoever stayed away from my custom, the angels opposed him on the Day of Resurrection and turned his face away from my basin.” [Mustadrak-ul-Wasāʾil, Volume 14 page 151]
