بم أدركت العلم ؟ قال : أدركت العلم بلسان سؤول ،وقلب عقول ، وبدن غير ملول
Ibn Abbas رضي الله عنهما was asked:
How did you gain your knowledge?
He said: I gained it with an inquisitive tongue, an understanding heart, and a body that does not tire.
sharh riyadus al-saaliheen shaykh Uthameen
‘Umar رضي الله عنهما said of him:
فقال لهم : ذاكم فتى الكهول له لسان سؤول وقلب عقول
This is for you a mature(with regards to his understanding of the deen) young boy, who has an inquisitive tongue, and an understanding heart.
Usool al-Tafseer shaykh Uthaymeen
And Ibn Abbas رضي الله عنهما said of himself:
قال ابن عباس: ذللت طالباً فعززت مطلوباً
I was lowered in my pursuit of knowledge.
So I became esteemed, when I was pursued.
