[الوصية بالتقوى :] أَمَّا بَعْدُ، فَإِنَّي أُوصِيكُمْ بِتَقْوَى اللهِ الَّذِي ابْتَدَأَ خَلْقَكُمْ، وَإِلَيْهِ يَكُونُ مَعَادُكُمْ، وَبِهِ نَجَاحُ طَلِبَتِكُمْ، وَإِلَيْهِ مُنْتَهْى رَغْبَتِكُمْ، وَنَحْوَهُ قَصْدُ سَبِيلِكُمْ، وَإِلَيْهِ مَرَامِي مَفْزَعِكُمْ، فَإِنَّ تَقْوَى اللهِ دَوَاءُ دَاءِ قُلُوبِكُمْ، وَبَصَرُ عَمَى أَفِئِدَتِكُمْ، وَشِفَاءُ مَرَضِ أَجْسَادِكُمْ، وَصَلاَحُ فَسَادِ صُدُورِكُمْ، وَطُهُورُ دَنَسِ أَنْفُسِكُمْ، وَجِلاَءُ عَشَا أَبْصَارِكُمْ، وَأَمْنُ فَزَعِ جَأْشِكُمْ، وَضِيَاءُ سَوَادِ ظُلْمَتِكُمْ.
[Advantages of fear of Allāh :] Now then, I advise you to fear Allāh, Who created you for the first time; towards Him is your return, with Him lies the success of your aims, at Him terminate (all) your desires, towards Him runs your path of right and He is the aim of your fears (for seeking protection). Certainly, fear of Allāh is the medicine for the sickness of your hearts, sight for the blindness of your spirits, the cure for the ailments of your bodies, the rectifier of the evils of your breasts, the purifier of the pollution of your minds, the light of the darkness of your eyes, the consolation for the fear of your heart and the brightness for the gloom of your ignorance.
