[فضائل الفرائض :] انْظُرُوا إِلَى مَا فِي هذِهِ الاْفْعَالِ مِنْ قَمْعِ نَوَاجِمِ الْفَخْرِ، وَقَدْعِ طَوَالِعِ الْكِبْرِ! وَلَقَدْ نَظَرْتُ فَمَا وَجَدْتُ أَحَداً مِنَ الْعَالَمِينَ يَتَعَصَّبُ لِشَيْء مِنَ الاْشْيَاءِ إِلاَّ عَنْ عِلَّة تَحْتَمِلُ تَمْوِيهَ الْجُهَلاَءِ، أَوْ حُجَّة تَلِيطُ بِعُقُولِ السُّفَهَاءِ غَيْرَكُمْ، فَإِنَّكُمْ تَتَعَصَّبُونَ لاِمْر مَا يُعْرَفُ لَهُ سَبَبٌ وَلاَ عِلَّةٌ. أَمَّا إِبْلِيسُ فَتَعَصَّبَ عَلَى آدَمَ لاِصْلِهِ، وَطَعَنَ عَلَيْهِ فِي خِلْقَتِهِ، فَقَالَ: أَنَا نَارِيٌّ وَأَنْتَ طِينِيٌّ.
Look what there is in these acts by way of curbing the appearance of pride and suppressing the traces of vanity. I cast my glance and noticed that no one in the world, except you, feels vanity for anything without a cause which may appeal to the ignorant, or a reason which may cling to the minds of the foolish, because you feel vanity for something for which no reason is discernable, nor any ground. As for Satan, he felt proud over Adam because of his origin and taunted at him about his creation, since he said: “I am of fire while you are of clay.”
