Nothing prevents any of you from meeting his brother who has a fault which he hates [and advising him to reform] except the fear that he too may meet you with a similar fault; indeed you have joined together in the love of this transitory [life] and have rejected the Hereafter. 31ـ ما يَمْنَعُ أحَدَكُمْ أنْ يَلْقى أخاهُ بِما يَكْرَهُ مِنْ عَيْبِهِ إلاّ مَخافَةُ أنْ يَلْقاهُ بِمِثْلِهِ قَدْ تَصافَيْتُمْ عَلى حُبِّ العاجِلِ ورَفْضِ الآجِلِ.

He who mentions your faults has not guarded you in your absence. 32ـ ما حَفِظَ غَيْبَكَ مَنْ ذَكَرَ عَيْبَكَ. He who points you to your faults and guards [your honour in] your absence has spared no efforts in advising you. 33ـ ما أَلاكَ جُهْداً فِي النَّصيحَةِ مَنْ دَلَّكَ عَلى عَيْبِكَ وحَفِظَ غَيْبَكَ. A person’s cognizance of his own faults is the most beneficial knowledge. 34ـ مَعْرِفَةُ المَرْءِ بِعُيُوبِهِ أنْفَعُ المَعارِفِ.

Never pursue the faults of people, for indeed if you think about it, you have of your own faults that which will keep you occupied from finding faults in others. 35ـ لاتَتَّبِعَنَّ عُيُوبَ النّاسِ فَإنَّ لَكَ مِنْ عُيُوبِكَ إنْ عَقَلْتَ ما يَشْغَلُكَ أنْ تَعيبَ أحَداً. Do not fault others for that which you do yourself, and do not punish (or rebuke) others for the sin that you permit yourself [to indulge in].

36ـ لاتَعِبْ غَيْرَكَ بِما تَأْتِيهِ، وَلاتُعاقِبْ (وَلا تُعاتِبْ) غَيْرَكَ بِذَنْب تُرَخِّصُ لِنَفْسِكَ فيهِ. Pursuing the faults [of others] is from the gravest evils. 37ـ تَتَتُّعُ العَوْراتِ مِنْ أعْظَمِ السَؤْآتِ. Pursuing the faults [of others] is from the most detestable of faults and worst evils. 38ـ تَتَبُّعُ العُيُوبِ مِنْ أقْبَحِ العُيُوبِ وشَـرِّ السَّيِّئاتِ. Whoever exposes his brother’s veil [and reveals his flaws], the faults of his own household (or family) get exposed.

39ـ مَنْ كَشَفَ حِجابَ أخيهِ اِنْكَشَفَ عَوْراةُ بَيْتِهِ(بَنِيهِ). One who pursues the faults of people, Allah exposes his own faults. 40ـ مَنْ تَتَبَّعَ عَوْراتِ النَّاسِ كَشَفَ اللّهُ عَوْرَتَهُ. One who seeks to learn about the secrets of his neighbour, his [own] curtains [of secrets] are torn apart. 41ـ مَنْ تَطَلَّعَ عَلى أسْرارِ جارِهِ اِنْهَتَكَتْ أسْتارُهُ. Whoever searches for the secrets of others, Allah uncovers his own secrets.
