HI Badal,
I see you also posted on https://salesforce.stackexchange.com/questions/392104/pass-list-attribute-from-lightning-component-to-apex-controller-and-fetch-record

Copying related code from above post:
You just need some Apex code to complete the project: 
public class MyController {
  @AuraEnabled public static sObject[] getRecords(String query) {
    return Database.query(query);
  }
}

And in your component markup: 
controller="MyController"

And in your doInit method: 
doInit: function(component, event, helper) {
  let action = component.get("c.getRecords");
  let query = component.get("v.Query");
  action.setParams({ query });
  action.setCallback(this, function(response) { 
    // Handle response here
  });
  $A.enqueueAction(action);
},

Please consider marking the answer as best to close the thread so others can find it helpful too. Thank you
