Shaykh Ubayd Al-Jabiree said “…Jihaad according to Ahlus-Sunnah – who have inherited from Prophet Muhammad (salallaahu ‘alaihi wa sallam) the correct understanding of the Deen, the correct understanding of ‘ibaadah (worship), and the correct understanding of social dealings – is of two categories: Jihadu Talab (Offensive Jihaad) and Jihaadu Dafi` (Defensive Jihaad).
And Jihadu Talab is to mobilize the troops and to dispath the armies and to prepare sufficient equipment in order to fight whosoever is surrounding them from the disbelievers – for the purpose of making the Word of Allaah uppermost. And this is from the special functions of the Muslim ruler. He is the one who can call to such an act and he is the one who sets it up, and he is the one who leads it himself. Or he appoints someone to lead a military detachment for it.
So whoever calls to Jihaad in a general manner, then he is one of two men: he is either ignorant concerning the fiqh of Jihaad, or he is a person of desires who is misguided and misguiding others – an innovator.
Regardless of whether he is from the former or the latter, it is obligatory upon the Ummah to be cautious of him and to have hatred for him, and it is obligatory upon the scholars to refute him and to warn against him.
The second [kind of Jihaad] is Jihaadu Dafi` (Defensive Jihaad), and it is to defend against the assailant and the transgressor.
So when an assailant and a transgressor from the disbelievers attacks the Muslim country, then it is permissible for the people of that country to defend themselves and to resist the attack in order to stop its evil and disprove its deception. And it is a required condition that they must have the ability and the strength to do this.
So if they have the ability and the strength, they can mobilize themselves to defend against the subjegation of the transgressing party and to defeat its [enemy’s] endeavor and to reject its tryanny.
And if they do not have the ability and the strength for that, then they have two choices: they can either flee with their religion and their honor to wherever they will be safe or they can seek a treaty of peace with this tyrannical enemy, and they can make contracts and agreements with him to preserve and safeguard the territory of the people of al-Islam.
So it is concluded from this that the required condition for Jihadu Talab (Offensive Jihaad) is the ruler, since it is from his special functions, and the required condition for Jihaadu Dafi` (Defensive Jihaad) is the strength and ability to carry it out. And strength and ability are necessary for both of these acts in order to defeat the endeavor of the enemies of Allaah.
