There is no wealth like intellect, no poverty like ignorance, no inheritance like adab, and no support like consultation.
لا غنى كالعقل، ولا فقر كالجهل، ولا ميراث كالأدب، ولا ظهير كالمشاورة
Lā ghinā ka'l-ʿaql, wa lā faqra ka'l-jahl, wa lā mīrātha ka'l-adab, wa lā ẓahīra ka'l-mushāwara
Ali, Nahj al-Balagha, saying 54 (Subhi Salih edition, p. 478; saying 54 in the Abduh edition). Nahj al-Balagha is a compilation without chains of transmission by al-Sharif al-Radi (d. 1015).
Four short measures.
There is no wealth like intellect.
There is no poverty like ignorance.
There is no inheritance like adab.
There is no support like seeking counsel.
Each one a door:
you look with intellect, speak with adab,
and walk by seeking counsel.
