وَاعْلَمْ يَا بُنَيَّ أَنَّ الرِّزْقَ رِزْقَانِ: رِزْقٌ تَطْلُبُهُ، وَرِزْقٌ يَطْلُبُكَ، فَإِنْ أَنْتَ لَمْ تَأْتِهِ أَتَاكَ. مَا أَقْبَحَ الْخُضُوعَ عِنْدَ الْحَاجَةِ، وَالْجَفَاءَ عِنْدَ الْغِنَى! إِنَّمَا لَكَ مِنْ دُنْيَاكَ مَا أَصْلَحْتَ بِهِ مَثْوَاكَ. وَإِنْ كُنْتَ جَازِعاً عَلَى مَا تَفَلَّتَ مِنْ يَدَيْكَ، فَاجْزَعْ عَلَى كُلِّ مَا لَمْ يَصِلْ إِلَيْكَ. اسْتَدِلَّ عَلَى مَا لَمْ يَكُنْ بِمَا قَدْ كَانَ، فَإِنَّ الْأُمُورَ أَشْبَاهٌ. وَلَا تَكُونَنَّ مِمَّنْ لَا تَنْفَعُهُ الْعِظَةُ إِلَّا إِذَا بَالَغْتَ فِي إِيلَامِهِ، فَإِنَّ الْعَاقِلَ يَتَّعِظُ بِالْآدَابِ، وَالْبَهَائِمَ لَا تَتَّعِظُ إِلَّا بِالضَّرْبِ.
Know O my child, that livelihood is of two kinds - a livelihood that you seek and a livelihood that seeks you, which is such that if you do not reach it, it will come to you. How bad it is to bend down at the time of need and to be harsh in riches. You should have from this world only that with which you can adorn your permanent abode. If you cry over what has gone out of your hands then also cry for what has not at all come to you. Infer about what has not yet happened from what has already happened, because occurrences are ever similar. Do not be like those whom preaching does not benefit unless you inflict pain on them, because the wise take instruction from teaching while beasts learn only from beating.
