وَقَدْ عَرَفْتُ أَنَّ مُعَاويَةَ كَتَبَ إِلَيْكَ يَسْتَزِلُّ لُبَّكَ، وَيَسْتَفِلُّ غَرْبَكَ، فاحْذَرْهُ، فَإِنَّمَا هُوَ الشَّيْطَانُ يَأْتِي الْمَرْءَ مِنْ بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِ، وَعَنْ يَمينِهِ وَعَنْ شِمَالِهِ، لِيَقْتَحِمَ غَفْلَتَهُ، وَيَسْتَلِبَ غِرَّتَهُ.
I have learnt that Mu‘āwiyah has written to you to deceive your wit and blunt your sharpness. You should be on guard against him because he is the Satan who approaches a believer from the front and from the back, from the right and from the left, to catch him suddenly in the hour of his carelessness and overcome his intelligence.
