Hurmat-e-Rasool(s.a.w) par Jaan bhi Qurbaan hai !
Yes you are right, its not good and fair if someone try to insult other's religious rights and customs in any way, its against the Order of Allah.If human has divided them into communities and groups then it doesn't mean that they should make their own separate Gods,there is only One God (Allah) and Muhammadpbuh is Messenger of Allah.We see that all humans of all the nations ,parts,countries,race, colors have same way of their birt, they have almost same desires,needs and thoughts for their life,it means and proves that all people have born by the same Creator, if there would be separate creators then we can say that all muslims should be different,christians should be different, hindus should be different,Jews should be different, because they are born (Allah save me and forgive me) by different Gods,but it is not like that ! we all human have same body,same eyes and ears but we have different thoughts which are grown up in our minds through our education and training which we get from our parents and our community and education, if there are different or more than one God, then there should be different humans having different eyes, different ears,different faces,different legs and hands, but it is not like this.
Some social sites like facebook is doing wrong by promoting such things which are against Muslims and their rights and faith(or any religion).I have come to know a social network which is owned by the muslims and providing positive atmosphere for all the people to communicate with each other which is
www.iemfriend.com ,its not a big site because it is in its early stages but is very good, i recommend it to all the muslims who like networking to join this site as it is obvious from its name "iemfriend" that its promoting International Electronic Muslims Friendship not only for muslims but for everyone !
