Yahya related to me from Malik that he had heard that Abdullah ibn Abbas said, "Equanimity, gentleness, and good behaviour are one twenty-fifth of prophecy."

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، أَنَّهُ كَانَ يَقُولُ الْقَصْدُ وَالْتُّؤَدَةُ وَحُسْنُ السَّمْتِ جُزْءٌ مِنْ خَمْسَةٍ وَعِشْرِينَ جُزْءًا مِنَ النُّبُوَّةِ ‏.‏
