In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Imaam As-Sadi [may Allaah have mercy upon him] said:
With regards to the Jihaad this religion brought, enjoining all good and forbidding all evil, which is the best type of Jihaad, the intent behind it is to repel the aggression of the aggressive people who seek to transgress against the rights of this religion and hinder its call. The intent behind it is not greed, covetousness or to fulfil personal desires of the soul. Whoever looks at the evidence of this principle, the biography of the Prophet [peace and blessings of Allaah be upon him] and his companions, and how they dealt with their enemies, he will know – without a doubt – that Jihaad is one of the necessities and it repels the enmity of the aggressors. (see appendix a)
The same applies to enjoining good and forbidding evil, because this religion cannot be established in an upright manner unless its followers adhere to its principles and practices, comply with its commands, which is the very goal behind righteousness, and avoid what it has prohibited, which are the evil and corrupt affairs. The adherents of this religion were committed to these matters, so that daring to engage in some of the forbidden deeds and shortcomings, and failing to perform the obligatory duties, which one is able to perform, is not made fair-seeming to some of them whose souls incline towards wrong doing, and that cannot be accomplished except through commands and prohibitions. This is one of the loftiest virtues of the religion and greatest necessities for its establishment, just as it also rectifies the criminals amongst its followers, discipline them and restrained them from vices, and guide them to lofty (praiseworthy) behaviour. (see appendix b)
As for giving them freedom without the divine restrictions – whilst they seek to adhere to the religion, subjected to its rulings and bound by its laws, this is one of the greatest acts of wrong doing and harm to them and society, especially to the obligatory duties which the Sharee’ah requires to be fulfilled, and are considered a requirement by sound intellect and customs (within the jurisdiction of the infallible divine revelation).
