مَنْ صَدَقَ لِسَانُهُ زَكَا عَمَلُهُ وَ مَنْ حَسُنَتْ نِيَّتُهُ زِيدَ فِي رِزْقِهِ وَ مَنْ حَسُنَ بِرُّهُ بِأَهْلِهِ زِيدَ فِي عُمُرِهِ. Everybody tells the truth by his tongue, his action will be corrected and everybody has got good intention, his sustenance will be increased and everybody behaves well with his family, his lifetime will be long.
