Imam Ali (AS) saw a man backbiting someone in the presence of his son, al-Hasan (AS), to whom he said, ‘O my son, steer your hearing clear of such a person, for verily he took the most repulsive thing from his mind and poured it into yours!
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) ـ وقد نَظَرَ إلى رجُلٍ يَغتابُ رجُلاً عندَ ابنِهِ الحسنِ (عَلَيهِ الّسَلامُ) ـ: يابُنَيَّ، نَزِّهْ سَمعَكَ عن مِثلِ هذا ؛ فإنّهُ نَظَرَ إلى أخبَثِ ما في وِعائهِ فَأفرَغَهُ في وِعائكَ!
