Nahj al-Balāgha
Hadith 1394أَمَّا بَعْدُ، فَقَدْ بَلَغَنِي عَنْكَ أَمْرٌ، إِنْ كُنْتَ فَعَلْتَهُ فَقَدْ أَسْخَطْتَ رَبَّكَ، وَعَصَيْتَ إِمَامَكَ، وَأَخْزَيْتَ أَمَانَتَكَ.
Now, I have come to know such a thing about you that if you have done so then you have displeased your Lord, disobeyed your Imām and betrayed your trust.
