Muslims believe that God revealed the Holy Qur'an to the Prophet Muhammad literally, word-for-word, in the Arabic language. Thus, Arabic is regarded as the holy language of Islam.

Languages of major Muslim groups

However, there is no single "Muslim language" per se, as Islam, the faith of Muslims, is shared by people of many different ethnicities and languages:

The Arabic language has many different 'branches'. Whether these are to be considered mere dialects or separate languages is a question of debate. The fact is, that it is not self-evident that all Arabic-speaking people understand each other when they speak. Each Arab country has developed its own variant of Arabic.

The Arabic spoken in Egypt is very well understood by most Arabic-speaking people. One of the reasons for this is the flourishing Egyptian film industry. Their films are watched by millions of people in the Arabic-speaking world. Another reason may be the leading rôle of the Al-Ahzar University in Cairo in theological issues and in the intellectual world. However, this does not mean an Egyptian will easily understand for instance an Arabic-speaking Moroccan. There many differences, not only in idioms, but in pronunciation and spelling as well. Egyptian Arabic is closer to Classical Arabic than Moroccan-Arabic is.
