Explanation of the author's statement: "Or one who conceals the truth, or one who is unable to express himself clearly, and all these matters are impossible in the speech of Allah and the speech of His Messenger (peace and blessings be upon him)

The Shaykh : Now, there is also the one who conceals the truth, the one who conceals the truth. What does "one who conceals the truth" mean? The one who conceals the truth is the deceiver who utters words while not intending them; he intends another meaning, but he deceives people and misleads them.
And the third is the one who is unable to express himself clearly; he cannot make it clear because he is incapable, he has a speech impediment.
All these three descriptions: ambiguity, concealment of the truth, and inability to express oneself clearly, "all these matters are impossible in the speech of Allah and the speech of His Messenger (peace and blessings be upon him), for their speech contains perfect clarity and intent. Therefore, the intended meaning is not to mislead creation or obscure things from them, nor is there any deficiency in clarity or eloquence in it".

So if we say that Allah the Exalted intended by His saying: that He has no attributes, is this clarity? This is the opposite of clarity.
