These verses bring together various aspects of Allah’s wisdom: His wisdom in creating us, His wisdom in guiding us, and His wisdom in judging our deeds. In doing so, these verses inspire in the believer’s heart a desire for righteousness and a feeling of hope.
First, Allah addresses His creating us in “the best of forms”. Whether we look at the human being’s physical construction, or consider the human potential, or the human soul and mind, we get a profound glimpse of Allah’s wisdom.
Consider how these two verses come together: “Indeed, We have created the human being upon the best of forms. Then we reduced him to the lowest of the low…”
One understanding of these two verses is that they describe the normal lifespan of the human being, how a person, after growing up to attain maturity and full strength, then ages and returns to a state of weakness.
Then the next verse reads: “except those who believe and do good, for they shall have an unending reward.”
Here Allah promises that after this life which must inevitably come to an end, there is an immense reward in the Hereafter for the righteous. Though all human beings are subject in this world to the laws of nature – everyone will age and die – the righteous will enjoy an eternal, blissful life in the Hereafter.
Then Allah says: “So who henceforth will give the lie to you about the faith?”
This is a rhetorical question. Can you not see that Allah has created the human being in such an excellent form? Aren’t there sufficient signs in this, and in everything else found in creation, to attest to Allah’s wisdom? Does this not compel us to believe in Him and worship Him?
Then Allah concludes by asking: “Is not Allah the Best of Judges?”
Here is further encouragement and reassurance to the righteous. It is an aspect of our faith is the belief that we will return to Allah in the next life and be judged for our deeds in the life of the world. This will also be a manifestation of Allah’s wisdom.
So when the Qur’an describes Allah as the “Best of Judges”, it is an affirmation of His perfect justice and immense mercy. Allah never wrongs anyone and is never oppressive. What He legislates for His servants is never burdensome and never unfair. Rather, the genuine teachings of Islam uphold the rights of all people without bias: the ruler and the ruled, the strong and the weak, the male and the female, the righteous and the sinner, the believer and the unbeliever. It upholds their rights in times of peace and times of war, and under all circumstances without exception.
This is why Muslims should refer to the Qur’an and the Sunnah of the Prophet (peace be upon him) for guidance in all aspects of their lives. They should do so as individuals to guide them in their personal lives, and they should do so as communities, societies, and nations for guidance in their political, social, and economic affairs.
Allah says: “As to those who believe and work righteousness, verily We shall not suffer to perish the reward of any who do a (single) righteous deed.” [Sūrah al-Kahf: 30]
Allah is Wise and He is the Best of Judges. In Islamic beliefs, no one is ever understood to bear the sin of another. No one is ever wronged by Allah. No sinner is ever punished for more than the magnitude of the sin committed and no good deed ever goes without a reward.
