Ahad is a direct Quranic name for boys that means “one”, “unique”, “matchless”. One of the names of Allah, subhanahu wa taala, is al-Ahad, and this name with the al- in front of it should not be used as a name because it is specific to Allah. But when you remove the al-, that is when you use Ahad by itself, it becomes a general and acceptable name to use. Ahad is used in about 80 places in the Quran.
