Adultery is stern offence and an act that invites Almighty Allah’s wrath. It is good that by the grace of Allah, you have asked Allah for forgiveness and now you feel regretful and have firmly resolved that in future you will never commit such acts. You should offer two rakah salah and seek Allah’s forgiveness extensively. It is hoped that Almighty Allah shall forgive you. After true tauba, Almighty Allah forgives the past sins and man becomes pure. It is mentioned in a hadith:
التائب من الذنب كمن لا ذنب له .
[A person who does tauba from sins is as if he has committed no sins.]
We pray for you and for your family. May Almighty Allah give you taufiq for good deeds and save you from sins and bless you with His pleasure and give you entry into paradise and save you from hellfire, Amen!
Allah (Subhana Wa Ta’ala) knows Best
