وَقَالَ (عليه السلام):
Amir al-mu'minin, peace be upon him, said:
لَأَنْسُبَنَّ الْإِسْلَامَ نِسْبَةً لَمْ يَنْسُبْهَا أَحَدٌ قَبْلِى
I am defining Islam as no one has defined before me:
الْإِسْلَامُ هُوَ التَّسْلِيمُ
Islam is submission,
وَ التَّسْلِيمُ هُوَ الْيَقِينُ
submission is conviction,
وَ الْيَقِينُ هُوَ التَّصْدِيقُ
conviction is affirmation,
وَ التَّصْدِيقُ هُوَ الْإِقْرَارُ
affirmation is acknowledgement,
وَ الْإِقْرَارُ هُوَ الْأَدَاءُ
acknowledgement is discharge (of obligations),
وَ الْأَدَاءُ هُوَ الْعَمَلُ .
and discharge of obligations is action.
