فاجْعَلُوا مَا افْتَرَضَ اللهُ عَلَيْكُمْ مِنْ طَلِبَتِكُمْ، وَاسْأَلُوهُ مِنْ أَدَاءِ حَقِّهِ مَا سَأَلَكُمْ، وَأَسْمِعُوا دَعْوَةَ الْمَوْتِ آذَانَكُمْ قَبْلَ أَنْ يُدْعَى بِكُمْ. إِنَّ الزَّاهِدِينَ في الدُّنْيَا تَبْكِي قُلُوبُهُمْ وَإِنْ ضَحِكُوا، وَيَشْتَدُّ حُزْنُهُمْ وَإِنْ فَرِحُوا، وَيَكْثُرُ مَقْتُهُمْ أَنْفُسَهُمْ وَإِنِ اغْتُبِطُوا بِمَا رُزِقُوا.
Include whatever Allāh has made obligatory on you in your demands. Ask from Him fulfilment of what He has asked you to do. Make your ears hear the call of death before you are called by death. Surely the hearts of the abstemious weep in this world even though they may (apparently) laugh, and their grief increases even though they may appear happy. Their hatred for themselves is much even though they may be envied for the subsistence they are allowed.
