العلم نور
فأرشَدَني إلى تَرْك المعاصي شَكَوتُ إلى وكيعٍ سوءَ حِفظي
ونورُ اللهِ لا يُهْدَى لِعاص وأخبرني بأنَّ العلمَ نور

Knowledge is light

Al-Waki', one of Imam al-Shafi'i's teachers, related from him that he said:

I complained to Waki` about my poor memory
So he adviced me leave sins

And told me that knowledgeis light
And Allah's light is not given to a sinner
