Who are Pagan ?
In the name of Allah , most gracious most merciful
Is sacrificing sinles a custom of satanists ?
Are idols (like in churches ) are customs of pagans ?
[Quran; 2:125] We have rendered the shrine (the Ka`aba) a focal point for the people, and a safe sanctuary. You may use Abraham's shrine as a prayer house. We commissioned Abraham and Ismail: "You shall purify My house for those who visit, those who live there, and those who bow and prostrate."
The History of Kaaba As A Place Of Worship
Kaaba, also known as, Ka'bah, Kabah and Caaba is the center of the holiest place of worship in Islam (Submission in English), i.e. the Sacred Mosque of Mecca, Al Masjid Al-Haram. Its name means the cube in Arabic as it is a cube shaped stone structure built in the middle of the Sacred Mosque. The Kaaba was built by prophet Abraham as a landmark for the House of God ,for the sole purpose of worshipping of God alone.
[2] As Abraham raised the foundations of the shrine, together with Ismail (they prayed): "Our Lord, accept this from us. You are the Hearer, the Omniscient.
Kaaba is the center of the circumambulations performed during the pilgrimage (hajj), and it is toward the Kaaba that Muslims face in their prayers (salat). Before prophet Muhammed's advent, Meccans who lost the religion of Abraham's monotheism, worshipped many idols, most notable of which were al-Lat, al-Uzza and Manat.
