Hadith n. 312

312. Amir al-mu'minin, peace be upon him, said: Sometimes the hearts move forward and sometimes they move backward. When they move forward get them to perform the optionals (as well), but when they move backward keep them confined to obligatories only.

312. وقال علی عليه السلام : إِنَّ لِلْقُلُوبِ إقْبَالاً وَإِدْبَاراً فَإِذَا أَقْبَلَتْ فَاحْمِلُوهَا عَلَى النَّوَافِلِ، وَإذَا أَدْبَرَتْ فَاقْتَصِرُوا بِهَا عَلَى الْفَرَائِضِ.
