Hawzah News Agency – Imam Ali peace be upon him says:

الشَّريفُ كُلُّ الشَّريفِ مَن شَرَّفَهُ عِلمُهُ، والسُّؤدُدُ حَقُّ السُّؤدُدِ لِمَنِ اتَّقى‏ اللَّهَ رَبَّهُ.

'The truly noble one is he who has been ennobled by his knowledge, and true chiefdom belongs to he who is wary of his duty to Allah, his Lord.'
