[Machine] Not to complain about your affliction, not to speak of your pain, and not to boast about yourself with your tongue.  

الزهد لأحمد:٧٧٣حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبِي حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يَزِيدَ الْمُقْرِئُ حَدَّثَنَا كَهْمَسُ عَنْ عَوْفٍ عَنْ رَجُلٍ قَالَ قَالَ أَبُو الدَّرْدَاءِ ثَلَاثٌ مِنْ مِلَاكِ أَمْرِ ابْنِ آدَمَ

أَنْ لَا تَشْكُوَ مُصِيبَتَكَ وَلَا تُحَدِّثَ بِوَجَعِكَ وَلَا تُزَكِّيَ نَفْسَكَ بِلِسَانِكَ
