YES ,religion only solution for the peace of the world. We everybody wants good things and peace of the world but peace cannot attained without adhering the teaching of true religion.The teaching of the Quran with which no culture or political system can compete,as an example ,one verse of the Quran presented here,-
"Verily, Allah enjoins justice, and doing good to others ,and giving to kith and kin,and forbid indecency , evil and transgression ."-chap-16, verse no-90..If the admonitions, in the above verse are heeded ,every country and nations would know nothing but peace and goodness.Allah exerts us to-
1] Abide by justice,
2] be benevolent
3]show compassion to others
4] refrain from and admonish others to refrain from such vices as can be harmful and known as blatant evil.
5] not transgress against beneficent ,in other words ,we should be just .Beneficent and compassionate. We should avoid indecency ,blatant evil, and transgression and should save others from falling prey to the evil.These are the basic commandments for the ultimate goodness and peace of the world.If these were put into practice than word can rid of all kid of disorder .
