Imam Ja‘far al-Ṣadiq (as): Wrongdoing is of three types: The wrongdoing that Allah forgives, the wrongdoing that Allah does not forgive and the wrongdoing that Allah does not leave uncounted. The wrongdoing that Allah does not forgive is associating partners with Him. The wrongdoing that is forgivable is the wrong that the servant commits against himself regarding that which is between him and Allah. And the wrongdoing that is not left uncounted is when people violate each other's rights in their dealings. al-Kāfī
