Eid is our big religious festival which we Muslims celebrate with great joy. In these two festivals, we forget our differences and rejoice. We have certain religious rules which we follow to observe these two festivals. Many of us are familiar with your childhood memories of Eid being a joyous time of all the cousins getting together and sharing stories. Now no one gives Eid cards, it was very popular earlier. Now only messages on mobile. Best wishes to you.
