What is the way to repentance and returning to Allah, to getting rid of repeated sin, to dealing with temptations and trials, and to facing feelings of despair regarding the acceptance of repentance, especially with the presence of magic and jinn possession?

Adultery is a grave sin, and if the woman is married, her sin is even greater. It is not permissible for her to seek a divorce in order to marry the man with whom she committed adultery. She must make sincere repentance and return to Allah, increase in acts of obedience and remembrance of Allah, show affection to her husband and adorn herself for him, strive in supplication, abandon all causes of temptation and sin, and stay away from bad company. She should also read the Qur’an and Sunnah to learn about the consequences of immoral acts and the encouragement to repent and feel modesty before Allah, while continuously being mindful of His constant watch over her. She must conceal her sin and not inform anyone about it. She should maintain her prayers and make her husband a support for her steadfastness.
