I was fatherless

Imaam Mu'ammar said:

أقام قتادة عند سعيد بن المسيب ثمانية أيام، فقال له في اليوم الثالث: ارتحل يا أعمى فقد أنزفتني
"Imaam Qataadah stayed with Sa'eed Ibn Musayyab for eight days and after the third day Sa'eed said to him: "O blind man, go elsewhere now, you have acquired all the knowledge I have".

["Siyar A'lam An-Nubala", 5/271].

Ash-Shaafi'ee:

"I was fatherless and my mother couldn't afford paper for me. When I found a bone, I wrote on it."

["Jami' Bayan-il-'ilm", 157].
