Selections from The Sayings and Preaching of Amir al-Muminin Ali ibn Abi Talib (Peace Be Upon Him) Including His Replies to Questions and Maxims Expressed for Various Purposes.
Translated by Sayyid Ali Reza

وَقَالَ (عليه ‏السلام):

Amir al-mu'minin, peace be upon him, said:

الرَّاضِي بِفِعْلِ قَوْمٍ

He who agrees with the action of a group of persons

كَالدَّاخِلِ فِيهِ مَعَهُمْ،

is as though he joins them in that action.

وَعَلَى كُلِّ دَاخِلٍ فِي بَاطِلٍ إِثْمَانِ:

And every one who joins in wrong commits two sins;

إِثْمُ الْعَمَلِ بِهِ،

one sin for committing the wrong

وَإِثْمُ الرِّضَى بِهِ.

and the other for agreeing with it.
