al-Sharif al-Radi (d. 406 AH) · Thaqalayn library edition, reproduced verbatim
آمَرَهُ بِتَقْوَى اللهِ فِي سَرَائِرِ أُمُورِهِ وَخَفِيَّاتِ عَمَلِهِ، حَيْثُ لَا شَهِيدَ غَيْرُهُ، وَلَا وَكِيلَ دُونَهُ.
He (Amīr al-mu’minīn) ordered him to fear Allāh in his secret matters and hidden actions, where there is no witness except He and no one watches save He.
