فَلَا تُطِعِ الْكَافِرِينَ وَجَاهِدْهُم بِهِ جِهَادًا كَبِيرًا (52)
(25:52) So, O Prophet, do not yield to the disbelievers, but wage a Jihad against them with this Qur'an. *67
*67) The Arabic words Jihad-i-Kabir imply three meanings:
(1) To exert one's utmost for the cause of Islam,
(2) To dedicate all one's resources to this cause, and
(3) To tight against the enemies of Islam on all possible fronts with all one's resources in order to raise high the "Word of Allah". This will include jihad with one's tongue, pen, wealth, life and every other available weapon .
