Well first of all Jiziya was not a war tax at all , it was a tax to humiliate non-muslims.
it can't be compared to war taxes imposed by rajputs, the rajput tax used to applied before war to raise additional money for preparing for war with muslims.it was for the countrys defence.while jiziya was an extortion. it was paid to save oneself from being killed or forcibly converted to islam.when payment of jiziya ceased,jihad resumed.
iam quoting a few verses from islams holy books:
Sura 9:29
------------------
stipulates that jizya be exacted from non-Muslims as a condition required for jihad to cease. Failure to pay the jizya could result in the pledge of protection of a dhimmi's life and property becoming void, with the dhimmi facing the alternatives of conversion, enslavement or death (or imprisonment, as advocated by Abu Yusuf, the chief qadi %u2014 religious judge %u2014 of Abbasid caliph Harun al-Rashid).
Ibn Kathir on Sura 9:29,
---------------------
writes that dhimmis must be:
disgraced, humiliated and belittled. Therefore, Muslims are not allowed to honor the people of the dhimma or elevate them above Muslims, for they [dhimmis] are miserable, disgraced, and humiliated.[107]
Al-Muwatta
--------------
Book 17, Number 17.24.46 states that Umar ibn Abd al-Aziz relieved those who converted to Islam from paying jizya. It also gives the sunnah on those who must pay jizya, principally non-Muslim males who have reached puberty, rather than zakat, as zakat is for the purpose of purifying Muslims, whereas jizya is for the purpose of humbling non-Muslims. It also outlines the additional jizya travelling traders must pay, and the rationale for that.
Al-Zamakhshari
----------------
, a Mutazili author of one of the standard commentaries on the Quran,[21] said that "the Jizyah shall be taken from them with belittlement and humiliation. The dhimmi shall come in person, walking not riding. When he pays, he shall stand, while the tax collector sits. The collector shall seize him by the scruff of the neck, shake him, and say "Pay the Jizyah!" and when he pays it he shall be slapped on the nape of the neck."[21]
Al-Mawardi (the famous Shafii jurist of Baghdad)
-------------------------------------------------
, stated in al-Ahkam as-Sultaniyyah (The Laws of Islamic Governance) that jizya is paid by the enemy in return for peace, and if the payment of jizya ceases, then jihad is resumed.[9]
