Nahj al-Balāgha|Volume 1|Book 2|Chapter 73
وَاعْلَمْ أَنَّ الشَّيْطَانَ قَدْ ثَبَّطَكَ عَنْ أَنْ تُرَاجِعَ أَحْسَنَ أُمُورِكَ، وَتَأْذَنَ لِمَقَالِ نَصِيحَتِكَ، وَالسَّلَامُ لِأَهْلِهِ.
Know that Satan has prevented you from turning to good actions and listening to the words of counsels. Peace be upon those who deserve it.
