a critical analysis of sunnites argument over non-necessity of khums(one fifth)

one of the practices, particularly important in shi'ism is to pay khums.somesunnites believe there is merely one verse in quran concerning khums; thus itisnot so important. this single verse includes the spoils of war, not business profitand trade as shiites believe in it. but shiites criticize sunnites argument asfollows: 1- firstly, there is more than one quranic verse regarding it, secondlyamong the verses on the leading ritual of hadj, we do rely on a single verse toprove it; henceforth, can't we apply this rule to khums? 3- the sunnitesthemselves refer to some narrations on paying khums. the consensus of muslimsto pay khums is one of the reasons given by shiites in response to sunnites,especially wahhabism. this research on one hand suggests the arguments raisedby shiites and on the other surveys the arguments of sunnites.the result of this research firmly asserts the weakness of sunnites argumentsand the strength of shiites' arguments as a religious duty.
