And when each of the two groups tastes its recompense in the Hereafter, and when everyone who hears the Qur'an tastes that he cannot bring anything that resembles it or comes close to it, he means by saying, confirming the revelation to them among the ignorant: "And indeed it" meaning the Qur'an or the recompense on the Day of Recompense "is the truth of certainty" meaning the established matter that is tasted and becomes [not -] accepting doubt, so it is certainty confirmed by the truth. This is from the addition of the attribute to the described, and it is above the knowledge of certainty. In this, there is an indication that the servant should strive to attain the knowledge of the truth so that he becomes a witness to the unseen as he witnesses the seen, for the matter of resurrection is witnessed every day in the night and the day and in the year in the plants and other than that.
