[The Words Ahad and Wāhid (“One”)]

As for their argument that the Quran’s description of Allah as ahad and wāhid implies the negation of His attributes—an argument they base on the denial of corporeality—they may be answered as follows:

Neither Arabic usage nor, indeed, the usage of speakers of languages generally establishes that an entity possessed of attributes cannot be called wāhid or ahad in negative or affirmative statements. On the contrary, overwhelmingly attested Arabic usage applies wāhid and ahad, in the contexts where these terms are used, as well as wahīd (“alone”), to entities possessed of attributes.

Allah Most High says:

“Leave Me with the one I created alone.”
[Al-Muddaththir: 11]

This refers to al-Walīd ibn al-Mughīrah.

Allah Most High also says:

“If they are daughters, two or more, they shall receive two-thirds of what he leaves; if there is only one, she shall receive half.”
[Al-Nisā’: 11]

Thus, He calls her “one,” although she is a single woman possessed of attributes—indeed, a body in which accidents inhere.

Allah Most High says:

“If any one of the polytheists seeks your protection, grant him protection so that he may hear the words of Allah.”
[Al-Tawbah: 6]

Allah Most High says:

“One of the two women said, ‘Father, hire him.’”
[Al-Qasas: 26]

Allah Most High says:

“so that if one of them errs, one of them may remind the other.”
[Al-Baqarah: 282]

Allah Most High says:

“If one of them transgresses against the other.”
[Al-Hujurāt: 9]
