If anybody wants to know what jihad is I can offer this authoritative description:
"09.0 JIHAD
(0: Jihad means to war against non-Muslims,
and is etymologically derived from the word
mujahada, signifying warfare to establish the
religion. And it is the lesser jihad. As for the
greater jihad, it is spiritual warfare against the
lower self (nafs), which is why the Prophet (Allah
bless him and give him peace) said as he was
returning from jihad,
"We have returned from the lesser jihad to
the greater jihad."
The scriptural basis for jihad, prior to
scholarly consensus (def: b7) is such Koranic
verses as:
(1) "Fighting is prescribed for you" (Koran
2:216);
(2) "Slay them wherever you find them"
(Koran 4:89);
(3) "Fight the idolators utterly" (Koran
9:36);
and such hadiths as the one related by Bukhari
and Muslim that the Prophet (Allah bless him and
give him peace) said:
"I have been commanded to fight people
until they testify that there is no god but Allah and
that Muhammad is the Messenger of Allah, and
perform the prayer, and pay zakat. If they say it,
they have saved their blood and possessions from
me, except for the rights ofIslam over them. And
their final reckoning is with Allah";
