Why oppose VANDE MATARAM?

HI,

we all are know very well that VANDE MATARAM in simple words means SALUTE TO THE MOTHER (land) i.e. our country or BHARAT MATA in other words.

before Independence,we have heard Gandhi,NEharu, Bhagatsingh and each n every Freedom Fighter saying VANDE MATARM as a Mantra..which motivated them to fight with British.

BUT..NOW…All of us must have read that some Islamic organizations have refused to sing VANDE MATARAM when Government has directed to sing it on 7th Sept.on the 100th year celebration of this song..

NOW CAN SOME ONE PLEASE EXPLAIN WHAT IS THE PROBLEM OF THESE ISLAMIC ORGANISATION IN SINGING VANDE MATARAM TO PRAISE OUR COUNTRY?
