Also it has been affirmed in Al-Mizan interpretation according to the words of scientists of literature that advantage (غنیمت) is any benefit that person gains from business, working or the war and although the point for descending of the verse is spoils of war but we know that never the point particularizes the generality of definition.[^5] It is concluded from all that has been said: The verse of advantage (غنیمت) has a vast meaning and consists of any kind of income, interest and benefit, because literal meaning of this word has a vast meaning and there is no clear proof about particularizing it in hand.
The only thing that some of Sunni commentators refer to, is that the verses before and after this verse are about Jihad and this matter shows that the verse of advantage (غنیمت) points to spoils of war in proportion.
While we know that the reasons of descending or the direction of discussion in Suras never particularize the generality of a verse; and in more clear way, there is no problem in that the meaning of the verse to be a general and overall definition while the reason of descending the verse is one sample of that general and overall concept.
And also in verse 233 of Sura Baqara: … لَا تُكَلَّفُ نَفْسٌ إِلَّا وُسْعَهَا … no soul shall have imposed upon it a duty but to the extent of its capacity; .. (2:233) has been mentioned as a general rule while the case for descending was about paying women who feeding babied and it has been ordered to the father of infant to pay according to his ability; but can reference of the verse to this special matter prevent the generality of this rule (not to do more than the ability)?!
Briefly, this verse has been said among the verses of Jihad but it says: Pay one fifth (Khums) of any income that you gain from any source (which one of them is spoils of war). Specially the relative word ” (any) and the word “شیء” (thing) which are two general and without any bond or condition words emphasize this matter. [^1]: Fakhr Raazi interpretation, vol. 15, page 164.
