In one verse, Allah describes the believers with these words: "Those who listen well to what is said and follow the best of it, they are the ones whom Allah has guided, they are the people of intelligence" (Surat az-Zumar, 18). Truly the faithful have intelligence and, consequently, heed His words and do their best.
In addition, we have used various examples from the Qur'an to point out that patience is one of the most important elements forming the foundation of superior morality and opening the door to countless blessings in this world and the next. We have invited all people of intelligence to be patient, in the full Qur'anic meaning of the word, and have brought the good news that people who adhere to morality and who always display a strong patience in order to earn Allah's approval will be rewarded in this world and in the afterlife.
Now, after all of these explanations, we conclude by reminding the readers that the finest reward a person can obtain in this world and the next is Allah's approval and mercy, and His Paradise. Such wonders cannot be compared with any of this world's pleasures and blessings. One way of gaining His love is to be aware of Allah's wisdom and bounty in every event, word, and act, and to trust in Allah, for the Qur'an tells us that He loves those who trust Him and show patience in all circumstances:
How many of the Prophets fought [in Allah's way], and with them [fought] large bands of godly men? But they never lost heart if they met with disaster in Allah's way, nor did they weaken (in will) or give in. And Allah loves those who are firm and steadfast. (Surah Al 'Imran, 146))
For these reasons, Allah declares that the faithful should race each other to acquire this morality: "O you who believe, persevere in patience and constancy, vie in such perseverance;strengthen each other, and heed Allah, so that hopefully you will be successful" (Surah Al 'Imran, 200).
In addition, remember that life comes and goes just as quickly for those who live morally as for those who do not. Those who exhibit impatience when facing the tests that Allah creates while they are in this world, who revolt against them by becoming impatient, and who are not constant in their morality and worship one day will die and find themselves between Heaven and Hell. Those who choose patience and surrender to Destiny spend their temporary life here in the finest possible way and will enter Paradise due to their trust in Allah. Those who spend their life being impatient, and complaining about their difficulties and troubles will find themselves in the darkness of Hell, just as they lived here in the darkness of irreligion, and will realize that they have sacrificed eternal life for a short temporary life on Earth.
This book seeks to warn such people before that day comes and before they say with great regret: "If only we had really listened and used our intellect, we would not have been Companions of the Blaze" (Surat al-Mulk, 10). It also invites everybody to live in the patience, which opens the way to all good things, and to vie with others in living this morality.
