His allies and messengers over their enemies, His doing away with them and replacing them with another people without this harming Him in the least, and His watching over all things—preserving, caring for, directing, and keeping account of them.

What sign, proof, or evidence could be better than the signs, proofs, and evidence of the prophets? These constitute Allah’s testimony on their behalf, which He has made abundantly clear and manifest to His servants through His words and deeds.

In an authentic report, the Prophet, may Allah bless him and grant him peace, said:

“There was no prophet who was not given signs such as would lead people to believe. What I have been given, however, is revelation that Allah has revealed to me. I therefore hope to have the most followers on the Day of Resurrection.”

Among His names, Most High, is al-Mu’min, which, according to one of its two interpretations, means the Confirmer: the One who confirms the truthful by establishing evidence of their truthfulness. He confirmed His messengers and prophets in what they conveyed from Him, and testified to their truthfulness through the proofs He brought into being by His decree and creation. For He, glorified be He, has declared—and His declaration is true, and His word is truth—that He will assuredly show His servants signs in the world around them and within themselves that make clear to them that the revelation conveyed by His Messenger is true. The Most High says:

“We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth.” [41:53]

That is, the Quran, for it is what was mentioned earlier in His words:

“Say: Have you considered: if it is from Allah and you then disbelieve in it…?” [41:52]

Then He says:

“Is it not sufficient that your Lord is a Witness over all things?” [41:53]

Thus, through His words, He testified on behalf of His Messenger that what he brought is true, and promised him that He would show His servants signs in His acts and creation that would also bear witness to this.

He then mentioned something greater and more exalted still: His being a Witness over all things. Among His names is al-Shahīd (the Witness), from whom nothing is absent and nothing escapes. Rather, He observes and witnesses everything, knowing it in all its detail.

This is an argument based on His names and attributes. The first is an argument based on His speech and words, while the argument from signs in the horizons and within ourselves is based on His acts and creation.
