This, too, was one of the arguments advanced by the Christians of Najrān against the Prophet—may God bless him and grant him peace. They appealed to the Almighty’s words inna (“Indeed We”) and naḥnu (“We”), insisting that such phrases prove He is three. But these belong to the ambiguous (mutashābih) texts they pursued in search of discord and forced interpretation, while neglecting the clear, decisive verses that allow only a single meaning. In all of His revealed scriptures God has plainly declared that He is one God, without partner and without equal.
His use of inna and naḥnu is an expression which, in every language, can refer either to someone who truly has partners and peers or to a single, majestic sovereign who is obeyed and who has helpers that carry out his commands, even though they are neither partners nor equals. God, exalted be He, created everything other than Himself; therefore it is impossible for Him to have a partner or a likeness. The angels and all created realms are but His armies. The Exalted says, “None knows the hosts of your Lord except Him” ⦗al-Muddaththir 74:31⦘, and He says, “To God belong the forces of the heavens and the earth, and God is All-Mighty, All-Wise” ⦗al-Fatḥ 48:7⦘.
If a single worldly king may say “We” and “Us” without meaning that there are three kings, then the Owner of sovereignty, Lord of the worlds, the Lord and Master of everything, is even more entitled to say “We” and “Us.” He has no partner and no peer; rather, to Him belong the hosts of the heavens and the earth.
