Thus the vile man realized that Allah had exposed him and laid bare his disgrace when he alleged that the word “Allah”—exalted is His praise—found in the Quran is nothing but a created name.
We said to the Jahmiyyah:
If someone were to swear a deliberate lie, saying, “By Allah, there is no deity but He,” he would, on your view, incur no perjury, because he would have sworn by a created thing rather than by the Creator. In this, Allah has disgraced him.
We also said to him:
Were not the Prophet—may Allah bless him and grant him peace—Abu Bakr, ʿUmar, ʿUthmān, ʿAlī, the caliphs after them, as well as the governors and judges, all accustomed to make people swear by the words, “By Allah, there is no deity but He”? According to your doctrine, they were all mistaken; in your estimation the Prophet—peace be upon him—and those after him should have made people swear by “the One whose name is Allah.”
Likewise, whenever they wished to utter the testimony, “There is no deity but Allah,” they would have had to say, “There is no deity except the One who created Allah”; otherwise, their profession of monotheism would be invalid. Thus Allah exposed him for the lie he attributed to Allah.
Rather, we say: Allah is Allah; “Allah” is not merely a name—names are entities distinct from Allah1. For if Allah did not speak, by what means did He create the creation?
