عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَمَّنْ ذَكَرَهُ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام )
أَنَّهُ نَظَرَ إِلَى بَعْضِ أَصْحَابِهِ وَ عَلَيْهِ نَعْلٌ سَوْدَاءُ فَقَالَ مَا لَكَ وَ لِلنَّعْلِ السَّوْدَاءِ أَ مَا عَلِمْتَ أَنَّهَا تُضِرُّ بِالْبَصَرِ وَ تُرْخِي الذَّكَرَ وَ هِيَ بِأَغْلَى الثَّمَنِ مِنْ غَيْرِهَا وَ مَا لَبِسَهَا أَحَدٌ إِلَّا اخْتَالَ فِيهَا .
1. A number of our people have narrated from Ahmad ibn Muhammad from ibn Mahbub from those whom he has mentioned who has said the following:
“Once abu ‘ Abd Allah 
, looked at one of his people who wore a black shoe. He (the Imam) said, ‘What have you to do with a black shoe, did you not know that it is harmful to the eyes, it slackens the penis, besides it is more expensive than others and whoever wears it, he shows arrogance in it?”’
