Will my sincere repentance for forbidden relationships and the precursors to adultery be accepted by Allah, and will the fears and anxieties that plague me concerning the disclosure of my matter disappear by relying on Allah, especially since I regret what has passed and am performing acts of obedience?

The repentant person must thank Allah for the blessing of repentance by remaining steadfast in righteousness, beneficial knowledge, good deeds, good company, abundant supplication, and trust in Allah. Among the suitable supplications are those seeking well-being and the supplication: "O Allah, we place You against their throats, and we seek refuge in You from their evils." Negative thoughts and fear of exposure must be repelled, and there must be trust in Allah that He will honor her with concealment, for this fear may be from Satan who loves to sadden the believer. There is no harm in saying "Allah is sufficient for me, and He is the best Disposer of affairs concerning them" if the intention is to seek refuge in Allah for protection from their evil and exposure. However, if the intention is to supplicate against them, then it is not permissible to supplicate against them if her action with them was by her choice and not under duress.
