Islam adheres to uncompromising monotheism. It teaches that God is One and indivisible. In the Quran, God often refers to Himself as “We”. But it does not mean that there is more than one God. The reference of God to Himself as “We” in many Quranic verses is necessarily understood in the Arabic language to denote power and grandeur, as opposed to the more intimate singular form, “I”, used in specific instances.
In some languages there are two types of plural form. One is related to quantity and used to refer to two or more persons, places or things. The other kind of plural is one of majesty, power and distinction. For example, in proper English, the Queen of England refers to herself as ‘we’. This is known as the ‘royal plural’. Rajeev Gandhi, the ex-Prime Minister of India used to say in Hindi, “Hum dekhna chahte hain”. “We want to see.” ‘Hum’ means ‘we’, which is again a royal plural in Hindi language. Similarly, when God refers to Himself in the Quran, He sometimes uses the Arabic word ‘nahnu’, meaning ‘We’. It does not indicate a plurality of number but the plurality of power and majesty.
The oneness of God is stressed throughout the Quran. A clear example is in this short chapter:
Say: He is Allah, the One and Only; Allah, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him.”
