THE CALL TO JIHAD (FIGHTING FOR ALLAH’S CAUSE) IN THE QUR’ AN
Ibn Qaiyyam said as regards the Statement of Allah: -
Verily, Allah has purchased of the believers their lives and their properties; for the price that their shall be the Paradise. They fight in Allah’s Cause, so they kill (others) and are killed. It is a promise in truth which is binding on Him in the Torah and the Gospel and the Qur’an. And who is truer to his covenant than Allah? Then rejoice in the bargain that you have concluded. That is the supreme success. (V.9: 111).
So Allah has put Paradise as the price of the believers and their properties, so if they sacrifice their lives and properties for His Cause, then they deserve the prize (Paradise) and the bargain that they concluded with Him. He reassured them with a number of assurances: (1) Allah informed them (believers) with a wording. “Surely”. (2) In wording of past tense as it had happened, and was confirmed and it remained as it was. (3) Moreover, He took upon Himself the responsibility of this convenant as He Himself bought the deal. (4) He informed that He has promised to give this price (Paradise) and shall neither break His Promise, nor shall neglect it. (5) It has come in wording of obligation and as information for His worshippers that it is a binding on Him. (6) He confirmed that it is indeed a binding on Him. (7) He has informed that it (this bargain) is written in the Best Books revealed from the heaven (i.e. the Torah, the Gospel, the Qur’an). (8) He informed them (His worshippers) in a wording of inquiry and denial that there is none Truer to his convenant than Him (Allah). (9) He the Glorified, the Most High ordered them to receive the glad tidings of this contract (bargain) and give the good news to one another (those) who concluded this contract (bargain) and stood firm on it [as they accepted no other alternative to it or committed anything that will cancel it (the deal)]. (10) He informed them a truly sure news that there is supreme success in the bargain (contract) which they have concluded. And bargain here means the thing which they shall receive with this price (their lives and properties) is Paradise.
And His (Allah’s) Statement: (Bargain which you have concluded) i.e. the price with which you have exchanged the deal, then Allah, the Glorified mentioned the kinds of people who have concluded this contract (deal) and not any other (as mentioned in His Statement):
(The believers whose lives Allah has purchased are) those who repent to Allah (from polytheism and hypocrisy,etc.), who worship Him, who praise Him, who observe Saum (fast) (or go out in Allah’s Cause), who bow down [in Salat (prayer)], who prostrate themselves (in prayer), who enjoin (people) for Al-Ma’ruf (i.e. Islamic Monotheism and all that Islam has ordained) and forbid (people) from Al-Munkar(i.e. disbelief, polytheism of all kinds and all that Islam has forbidden), and who observe the limits set by Allah (do all that Allah has ordained and abstain from all kinds of sins and evil deeds which Allah has forbidden). And give glad tidings to the believers.(V.9:112)
