"Both the Qur'an and the Hadith have attached great importance to jihad. What is jihad? Jihad means struggle, to struggle one's utmost. It must be appreciated at the outset that this word is used for non-violent struggle as opposed to violent struggle. One clear proof of this is the verse of the Qur'an (25:52) which says: "Perform jihad with this (i.e., the word of the Qur'an ) most strenuously.""
