وَالصَّبْرُ مِنْهَا عَلَى أَربَعِ شُعَبٍ: عَلَى الشَّوْقِ وَالشَّفَقِ وَالزُّهْدِ وَالتَّرَقُّبِ: فَمَنِ اشْتَاقَ إِلَى الْجَنَّةِ سَلاَ عَنِ الشَّهَوَاتِ، وَمَنْ أشْفَقَ مِنَ النَّارِ اجْتَنَبَ الْـمُحَرَّمَاتِ، وَمَنْ زَهِدَ فِي الدُّنْيَا اسْتَهَانَ بِالْمُصِيبَاتِ، وَمَنِ ارْتَقَبَ الْمَوْتَ سَارَعَ إِلَى الْخَيْرَاتِ.
Endurance again has four aspects: eagerness, fear, abstention (from the world) and anticipation (of death). So, whoever is eager for Paradise will ignore the passions; whoever fears the Fire (of Hell) will refrain from prohibited acts; whoever abstains from the world takes hardships lightly; and whoever anticipates death will hasten towards good deeds.
