The Peak of Eloquence · Hadith 1230 (#Passage #39)
Chapter 10 | To Muawiya
وَقَدْ دَعَوْتَ إِلَى الْحَرْبِ، فَدَعِ النَّاسَ جَانِباً وَاخْرُجْ إِلَيَّ، وَأَعْفِ الْفَرِيقَينِ مِنَ الْقِتَالِ، لِتَعْلَمَ أيُّنَا الْمَرِينُ عَلَى قَلْبِهِ، وَالْمُغَطَّى عَلَى بَصَرِهِ!
You have called me to war. Better to leave the people on one side, come out to me and spare both the parties from fighting so that it may be known who of us has a rusted heart, and covered eyes.
