وَ قَالَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ: "جُمِعَ اَلْخَيْرُ كُلُّهُ فِي ثَلاَثِ خِصَالٍ اَلنَّظَرِ وَ اَلسُّكُوتِ وَ اَلْكَلاَمِ فَكُلُّ نَظَرٍ لَيْسَ فِيهِ اِعْتِبَارٌ فَهُوَ سَهْوٌ وَ كُلُّ كَلاَمٍ لَيْسَ فِيهِ ذِكْرٌ فَهُوَ لَغْوٌ وَ كُلُّ سُكُوتٍ لَيْسَ فِيهِ فِكْرَةٌ فَهُوَ غَفْلَةٌ فَطُوبَى لِمَنْ كَانَ نَظَرُهُ عَبَراً وَ سُكُوتُهُ فِكْراً وَ كَلاَمُهُ ذِكْراً وَ بَكَى عَلَى خَطِيئَتِهِ وَ أَمِنَ اَلنَّاسُ شَرَّهُ".
Commander of the Faithful Imam Ali ibn Abi Talib (a.s) said: "All goodness has been gathered in three qualities: looking, silence, and speech. Every glance that lacks reflection is heedlessness, every speech without the remembrance (of Allah (swt)) is idle talk, and every silence without contemplation is neglect. Glad tidings are for the one whose gaze is reflective, whose silence is thoughtful, whose speech is in remembrance, who weeps over his sins, and from whose harm people are safe."
