وَقَالَ (عليه السلام):
Amir al-mu'minin, peace be upon him, said:
الْكَلاَمُ فِي وَثَاقِكَ مَا لَمْ تَتَكَلَّمْ بِهِ،
Words are in your control until you have not uttered them;
فَإذَا تَكَلَّمْتَ بِهِ صِرْتَ فِي وَثَاقِهِ،
but when you have spoken them out you are under their control.
فَاخْزُنْ لِسَانَكَ كَمَا تَخْزُنُ ذَهَبَكَ وَوَرِقَكَ
Therefore, guard your tongue as you guard your gold and silver,
فَرُبَّ كَلِمَةٍ سَلَبَتْ نِعْمَةً وَجَلَبَتْ نِقْمَةً.
for often one expression snatches away a blessing and invites punishment.
