Of the thousands of examples of the category of proof, is the verse:

So consider the signs of God’s mercy; how He gives life to the earth after its death. Indeed, it is He Who gives life to the dead, for He is powerful over all things.(30:50)

Its exposition is such in proving resurrection and banishing doubts that it could not be more clearly demonstrated. It is like this: it says that, as is proved and explained in the Ninth Truth of the Tenth Word and in the Fifth Flash of the Twenty-Second Word, every spring examples of resurrection are provided in three hundred thousand ways in the earth being raised to life with the utmost order and differentiation despite the innumerable species being all mixed up together in total confusion, thus demonstrating to the human observer that the resurrection of the dead would not be difficult for the One who does this. Also, since to write without fault or error with the pen of power hundreds of thousands of species on the page of the earth, all together and one within the other, is the seal of the Single One of Unity; with this verse it both proves divine unity as the clearly as the sun, and it demonstrates the resurrection of the dead as easily and decisively as the rising and setting of the sun. Thus, the Qur’an indicates this truth in regard to the manner of its occurrence, as described by the word “how”, just as it mentions it in detail in many suras.

And for example, in the sura, “Qaf. By the Glorious Qur’an”(50:1), it proves resurrection in such a brilliant, fine, sweet, and exalted manner that it convinces as certainly as the coming of spring. Look! In answer to the unbelievers denying the raising to life of decomposed bones and saying: “This is extraordinary; it could not be!”, it decrees:

Do they not look to the skies above them; how we have made them and adorned them and how there is no flaw in them... until: ... and thus will be the Resurrection.(50:6-11)

Its manner of exposition flows like water and shines like the stars. It gives both pleasure and delight to the heart like dates. And it is sustenance.

And in one of the most subtle examples of the category of proof, it says:

Ya. Sin.∗ By the All-Wise Qur’an ∗ Indeed you are one of the messengers.(36:1-3)

That is, “I swear by the Wise Qur’an that you are one of the divine messengers.” This oath indicates that the proof of messengership is so certain and true and its veracity is so worthy of honour and respect, that it is sworn by. By indicating this, it is saying: “You are the Messenger, for you hold the Qur’an in your hand, and the Qur’an is the truth and it is the word of Truth. For it contains true wisdom and bears the seal of miraculous inimitability.”
