Yes, Allah (SWT) is the Most Forgiving and Most Merciful, and He will forgive private sins if one sincerely repents.
Allah (SWT) emphasizes the importance of repentance (Tauba) in the Quran. He encourages believers to turn to Him in repentance for their wrongdoings, both public and private. The key to receiving Allah's forgiveness lies in sincere repentance, which includes:
- Acknowledging the sin: Recognizing and admitting the wrongdoing committed.
- Feeling remorse: Experiencing sincere regret and sorrow for the sin.
- Seeking forgiveness: Asking Allah (SWT) for forgiveness directly.
- Making a firm resolution not to repeat the sin: Committing to avoiding the sin in the future.
- Attempting to rectify the harm caused (if applicable): If the sin involved harming others, making an effort to make amends.
Even if a sin is committed in private, away from the eyes of others, it is still known to Allah (SWT). Therefore, sincere repentance is necessary for seeking His forgiveness. Allah's mercy encompasses all sins, no matter how great, provided that the repentance is genuine.
It is important to understand that relying solely on the hope of forgiveness without making a genuine effort to repent and change one's behavior is not sufficient. Repentance must be accompanied by a sincere desire to please Allah (SWT) and to live a life that is pleasing to Him.
In summary, Allah (SWT) will forgive private sins if one sincerely repents, fulfilling the conditions of repentance and striving to avoid repeating the sin.
