Translated by Sayyid Ali Reza

وَقَالَ (عليه ‏السلام):

Amir al-mu'minin, peace be upon him, said:

إِنَّ اللهَ سُبْحَانَهُ جَعَلَ الطَّاعَةَ غَنِيمَةَ الاْكْيَاسِ عِنْدَ تَفْرِيطِ الْعَجَزَةِ.

When the disabled fall short in performing acts of obedience to Allah, the Glorified, it is a good opportunity given by Allah for the intelligent to perform such acts.
