al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
وَاعْلَمُوا أَنَّ مَا كُلِّفْتُمْ [بِهِ] يَسِيرٌ، وَأَنَّ ثَوَابَهُ كَثِيرٌ، وَلَوْ لَمْ يَكُنْ فِيمَا نَهَى اللهُ عَنْهُ مِنَ الْبَغْيِ وَالْعُدْوَانِ عِقَابٌ يُخَافُ لَكَانَ فِي ثَوَابِ اجْتِنَابِهِ مَا لَا عُذْرَ فِي تَرْكِ طَلَبِهِ.
You should know that the obligations laid on you are few, while their reward is much. Even if there had been no fear of punishment for revolt and disobedience, which Allāh has prohibited, the reward in keeping aloof from it would be enough (incentive) to abstain from going after it.
