Ibn al-Jawzī رحمه الله: “O youth, the essence of your soul lies in seeking knowledge, and the adornment of your soul is acting upon what you learnt. Whoever does not act upon his knowledge will never recognise the value of what he possesses; he will be like a person carrying musk perfume but is unable to smell it because he has the flu.” [Seeds of Admonishment & Reform | Pg. 121]
