(English) In the Koran we read: “The most beautiful names belong to Allah. So call on him by them” (surah 7.180). “The most beautiful names” are understood by Muslim theologians as names and attributes of God which are used during prayer, Sufi-meditation or while saying the rosary. God’s names are important as God has not revealed himself in Islam, as Muslim theologians hold, but has only sent down his Holy Book, the Koran.
