سورة Al-Hajj ( The Pilgrimage ) - الآية 25

Verily! Those who disbelieve and hinder (men) from the Path of Allah, and from Al-Masjid-al-Haram (at Makkah) which We have made (open) to (all) men, the dweller in it and the visitor from the country are equal there [as regards its sanctity and pilgrimage (Hajj and 'Umrah)]. And whoever inclines to evil actions therein or to do wrong (i.e. practise polytheism and leave Islamic Monotheism), him We shall cause to taste a painful torment.
