فَتَفَهَّمْ يَا بُنَيَّ وَصِيَّتِي، وَاعْلَمْ أَنَّ مَالِكَ الْمَوْتِ هُوَ مَالِكُ الْحَيَاةِ، وَأَنَّ الْخَالِقَ هُوَ الْمُمِيتُ، وَأَنَّ الْمُفْنِيَ هُوَ الْمُعِيدُ، وَأَنَّ الْمُبْتَلِيَ هُوَ الْمُعَافِي، وَأَنَّ الدُّنْيَا لَمْ تَكُنْ لِتَسْتَقِرَّ إِلَّا عَلَى مَا جَعَلَهَا اللهُ عَلَيْهِ مِنَ النَّعْمَاءِ، وَالِابْتِلَاءِ، وَالْجَزَاءِ فِي الْمَعَادِ، أَوْ مَا شَاءَ مِمَّا لَا تَعْلَمُ، فَإِنْ أَشْكَلَ عَلَيْكَ شَيْءٌ مِنْ ذلِكَ فَاحْمِلْهُ عَلَى جَهَالَتِكَ، فَإِنَّكَ أَوَّلُ مَا خُلِقْتَ بِهِ جَاهِلًا ثُمَّ عُلِّمْتَ، وَمَا أَكْثَرَ مَا تَجْهَلُ مِنَ الْأَمْرِ، وَيَتَحَيَّرُ فِيهِ رَأْيُكَ، وَيَضِلُّ فِيهِ بَصَرُكَ ثُمَّ تُبْصِرُهُ بَعْدَ ذلِكَ! فَاعْتَصِمْ بِالَّذِي خَلَقَكَ وَرَزَقَكَ وَسَوَّاكَ، وَلْيَكُنْ لَهُ تَعَبُّدُكَ، وَإِلَيْهِ رَغْبَتُكَ، وَمِنْهُ شَفَقَتُكَ.
Appreciate my advice, O’ my child, and know that He Who is the Master of death is also the Master of life, that the Creator causes death as well; that He Who destroys is also the restorer of life and that He Who inflicts disease is also the curer. This world continues in the way Allāh has made it with regard to its pleasures, trials, rewards on the Day of Judgement and all that He wishes and you do not know. If anything of this advice is not understood by you then attribute it to your ignorance of it, because when you were first born you were born ignorant. Thereafter, you acquired knowledge. There are many matters of which you are ignorant and in which your sight first wonders and your eye wanders then after this you see them. Therefore, cling to Him Who created you, fed you and put you in order. Your worship should be for Him, your eagerness should be towards Him and your fear should be of Him.
