Seeking forgiveness through prayer after faults
Nahj al-Balāgha|Volume 1|Book 3|Chapter 299
٢٩٩. وَقَالَ (عليه السلام): مَا أَهَمَّنِي ذَنْبٌ أُمْهِلْتُ بَعْدَهُ حَتَّى أُصَلِّيَ رَكْعَتَيْنِ وَأسْأَلَ اللهَ الْعَافِيَة.
299. Amīr al-mu’minīn, peace be upon him, said: I am not worried by a fault after which I get time to offer prayer in two units (rak‘ah) and beg safety from Allāh.
