Assalamu Alaikum Dear Brothers and Sisters,

recently i came across an article which stated some people in Switzerland had buried dead pigs and poured pigs’ blood on a land which a Masjidh was supposed to be built. The article, being an anti-Islamic one continued to say that it was a very clever move by those people since 'Muslims consider pig as a flighty animal and hence they are forbidden to build mosques where pig parts are found'.

what is the truth in this ? is it forbidden in islam to build a mosque on a ground where pigs were buried ?
