What you mean punjab belongs to sikhs? how?....... Punjab is the cradle of Hindu-sanatan civilisation...... it is where the the ancient vedas were composed and the mahabharat took place many thousands of years ago. The punjab was known in ancient times as sapta sindhu (land of seven rivers)... and anyway sikhs have never been a majority in punjab until punjab was carved out of himachal and haryana, infact if you put together the original punjab, sikhs will be about 20% max only.
