فَأَصْلِحْ مَثْوَاكَ، وَلَا تَبِعْ آخِرَتَكَ بِدُنْيَاكَ، وَدَعِ الْقَوْلَ فِيمَا لَا تَعْرِفُ، وَالْخِطَابَ فِيمَا لَمْ تُكَلَّفْ، وَأَمْسِكْ عَنْ طَرِيقٍ إِذَا خِفْتَ ضَلاَلَتَهُ فَإِنَّ الْكَفَّ عِنْدَ حَيْرَةِ الضَّلاَلِ خَيْرٌ مِنْ رُكُوبِ الْأَهْوَالِ.
Therefore, plan for your place of stay and do not sell your next life with this world. Give up discussing what you do not know and speaking about what does not concern you. Keep off the track from which you fear to go astray because refraining (from moving) when there is fear of straying is better than embarking on dangers.
