And when Ghafir was concluded with that the disbelievers argued about the verses of Allah with falsehood. They rejoiced in what they had of the apparent knowledge of the worldly life. When the hardship came, they detached themselves from it and disavowed it, returning to what the messengers brought, but it was not accepted from them. So he knew that any knowledge that does not benefit in times of hardship and adversity is not knowledge, rather ignorance is better than it. This was difficult for the Prophet, blessings and peace be upon him, out of fear that the end of his nation would be destruction, while they persisted in disbelief until the hardship came. And that his most common state was warning. Glorified is He, He began this surah by stating that this Qur'an is a mercy for whoever has knowledge and has the strength that necessitates his standing in what benefits him. He repeated the description of mercy in the attribute of generality and the attribute of specificity, indicating that most of the nation is mercied. He informed that the Book was detailed in detail and clarified in clarification, and that the argument of the debater does not harm it, nor the plotting of the schemer. And that it suffices with the inability of creation to propose verses. He said, informing about a beginning: "A revelation" meaning: according to the gradualness, it is great. "From the Most Gracious" meaning: the One who has general mercy for the disbeliever and the believer by sending down the books and sending the messengers. "The Most Merciful" meaning: the One who specifically grants His mercy to the believers by obligating them with what pleases Him about them.
