و درود خدا بر او فرمود: سخت ترین گناه آن است که گناهکار آن را کوچک شمارد. Amir al-Mu'minin, peace be upon him, said: The most serious sin is which the doer considers if light.

وَ قَالَ (عليه السلام): أَشَدُّ الذُّنُوبِ مَا اسْتَهَانَ بِهِ صَاحِبُهُ

Amir al-Mu'minin, peace be upon him, said: The most serious sin is which the doer considers if light.
