وَقَالَ (عليه السلام):
Amir al-mu'minin, peace be upon him, said:
الْعِلْمُ عِلْمَانِ:
Knowledge is of two kinds –
مَطْبُوعٌ وَمَسْمُوعٌ
that which is absorbed and that which is just heard.
وَلاَ يَنْفَعُ الْمَسْمُوعُ
The one that is heard does not give benefit
إِذَا لَمْ يَكُنِ الْمَطْبُوعُ.
unless it is absorbed.
