يَا جَابِرُ، قِوَامُ الدِّينِ وَالدُّنْيَا بِأَرْبَعَةٍ: عَالِمٍ مُسْتَعْمِلٍ عِلْمَهُ، وَجَاهِلٍ لَا يَسْتَنْكِفُ أَنْ يَتَعَلَّمَ، وَجَوَادٍ لَا يَبْخَلُ بِمَعْرُوفِهِ، وَفَقِيرٍ لَا يَبِيعُ آخِرَتَهُ بِدُنْيَاهُ؛ فَإِذَا ضَيَّعَ الْعَالِمُ عِلْمَهُ اسْتَنْكَفَ الْجَاهِلُ أَنْ يَتَعَلَّمَ، وَإِذَا بَخِلَ الْغَنِيُّ بِمَعْرُوفِهِ بَاعَ الْفَقِيرُ آخِرَتَهُ بِدُنْيَاهُ.
O’ Jābir, the mainstay of religion and the world are four persons: The scholar who acts on his knowledge; the ignorant who does not feel ashamed of learning; the generous who is not niggardly in his favours; and the destitute who does not sell his next life for his worldly benefits. Consequently, when the scholar wastes his knowledge, the ignorant feels shame in learning; and when the generous is niggardly with his favours, the destitute sells his next life for the worldly benefits.
