٤ـ عَنْهُ عَنْ عُثْمَانَ بْنِ عِيسَى قَالَ حَضَرْتُ أَبَا الْحَسَنِ صَلَوَاتُ الله عَلَيْهِ وَقَالَ لَهُ رَجُلٌ أَوْصِنِي فَقَالَ لَهُ احْفَظْ لِسَانَكَ تُعَزَّ وَلا تُمَكِّنِ النَّاسَ مِنْ قِيَادِكَ فَتُذِلَّ رَقَبَتَكَ‏.
4. It is narrated from him (narrator of the Hadith above) from ‘Uthman ibn ‘Isa who has said the following: “Once I was in the presence of abu al-Hassan  and a man said, ‘Please teach me good advice.’ The Imam said, ‘Control your tongue and you will be respected and do not allow people to lead you to humiliation.’”
