Reference: Jāmi’ Bayān al-‘ilm wa Fadlihī
أَخِـي لَنْ تَنَالَ العِلمَ إِلَّا بِسِتَّةٍ … سَأُنْبِیكَ عَنْ تَفصِیلِهَا بِبَیَانِ
“My brother, you will never attain knowledge except with six…
I will inform you of their details with clarity;
ذَكَاءٌ وحِرصٌ وَاجتِهَادٌ وَبُلغَةٌ … وصُحبَةُ أُستَاذٍ وَطُولُ زَمَانِ
Intelligence, enthusiasm, striving hard and sustenance…
the companionship of a teacher, and a long time.”
~ Muḥammad Ibn Idrīs ash-Shāfi’ī [d: 206h]
