- to make the whole of Arabia a perfect Dar-ul-Islam [abode of Islam],
- to extend the influence of Islam to the adjoining countries,
- to crush the mischief of the hypocrites, and
- to prepare the Muslims for Jihad against the non- Muslim world.
In order to enable the Muslims to extend the influence of Islam outside Arabia, they were enjoined to crush with sword the non- Muslim powers and to force them to accept the sovereignty of the Islamic State. As the great Roman and Iranian Empires were the biggest hindrances in the way, a conflict with them was inevitable. The object of Jihad was not to coerce them to accept Islam they were free to accept or not to accept it-but to prevent them from thrusting forcibly their deviations [non-Islamic religions] upon others and the coming generations. The Muslims were enjoined to tolerate their misguidance only to the extent that they might have the freedom to remain misguided, if they chose to be so, provided that they paid Jizyah (v. 29) as a sign of their subjugation to the Islamic State.
In order to prepare the Muslims for Jihad against the whole non-Muslim world, it was necessary to cure them even of that slight weakness of faith from which they were still suffering. For there could be no greater internal danger to the Islamic Community than the weakness of faith, especially where it was going to engage itself single-handed in a conflict with the whole non-Muslim world. That is why those people who had lagged behind in the Campaign to Tabuk or had shown the least negligence were severely taken to task, and were considered hypocrites if they had no plausible excuse for not fulfilling that obligation. Moreover, a clear declaration was made that in future the sole criterion of a Muslim's faith shall be the exertions he makes for the uplift of the Word of Allah and the role he plays in the conflict between Islam and kufr. Therefore, if anyone will show any hesitation in sacrificing his life, money, time and energies, his faith shall not be regarded as genuine. This is a reference to verses 9:81-96.
