I had asked Allah for forgiveness of a particular sin and had sworn by Allah that I wouldn't do it again and I should be given a huge punishment if I do. I did the sin again today and now I feel very worried. Is there any hope for me now?
Allah The Glorious, The Forgiver, The Most Merciful, Most Compassionate Has kept the gate of repentance open for all sinners who really and sincerely repent and decide not to commit the sin again. If they do it again, the gate of forgiveness will not be closed if they sincerely repent.
Keep on seeking forgiveness and never loose hope in The Mercy of Allah.
Wassalam.
