Abbas - Tanwîr al-Miqbâs min Tafsîr Ibn ‘Abbâs
(Then went he forth) i.e. Korah (before his people in his pomp) his horses, mules, servant boys and servant girls, attires of gold and silver and different kinds of arms and clothes. (Those who were desirous of the life of the world said: Ah, would that unto us had been given the like of what has been given unto Korah) of wealth! (Lo! he is lord of rare good fortune.
So he, Korah, emerged before his people in his finery, with his large retinue [all of them] in procession dressed in gold and silk garments and mounted on adorned horses and mules. Those who desired the life of this world said, ‘O (yā is for drawing attention) would that we had the like of what Korah has been given, this world. Truly he enjoys great fortune’, abundant [fortune] in it.
How Qarun went forth in His Finery, and His People's Comments
Allah tells us how Qarun went forth one day before his people with his magnificent regalia; wearing his fine clothes, accompanied by his fine horses, his servants and retinue. When those whose desires and inclinations were for the world saw his adornments and splendor, they wished that they could have the same as he had been given, and said:
(Ah, would that we had the like of what Qarun has been given! Verily, he is the owner of a great fortune.) meaning, `he is very lucky and has a great share in this world.' When the people of beneficial knowledge heard this, they said to them:
(Woe to you! The reward of Allah is better for those who believe and do righteous deeds,) `Allah's reward to His believing, righteous servants in the Hereafter is better than what you see,' as is reported in the authentic Hadith:
(Allah has prepared for His righteous servants what no eye has seen, no ear has heard, and the heart of a human cannot comprehend. Recite, if you wish: (No person knows what is kept hidden for them of joy as a reward for what they used to do.)) (32:17).
وَلاَ يُلَقَّاهَآ إِلاَّ الصَّـبِرُونَ
(and this none shall attain except the patient.) As-Suddi said: "None shall reach Paradise except for the patient'' -- as if this were the completion of the statement made by the people of knowledge. Ibn Jarir said, "This applies only to those who patiently forsake the love of this world, seeking the Hereafter. It is as if this is part of what the people of knowledge said, but it is made part of the Words of Allah, stating this fact.''
Maududi - Sayyid Abul Ala Maududi - Tafhim al-Qur'an
That is, "'This kind of character and the way of thinking and the bounty of Allah's reward falls to the lot of only those who stick firmly and steadfastly and patiently to the lawful ways in life, whether by so doing they are able to earn only a bare living, or are enabled to become millionaires, but are never inclined to follow the unlawful ways even if they promise all the benefits and wealth of the world. In this verse, "Allah's reward" means the bounteous provision that is gained by man in the world and the Hereafter as a result of labor and toil undertaken within the bounds set by Allah; and "patience" means to have control over one's emotions and desires, to stick to honesty and righteousness as against greed and lust, to bear the losses that one may have to incur on account of the truth and justice, to spurn the gains that might accrue from employing unlawful devices, to remain content and satisfied with the lawful earning even if it is meager and insufficient, to eschew feelings of envy and jealousy at the splendor of the corrupt people and avoid ;even casting a glance at it, and to be satisfied with the thought that for an honest man the colorless purity that Allah has granted him by His grace is better than the lustrous filth of evil and corruption. As for "fortune", it implies Allah's reward as well as the pure mentality by virtue of which a believing and righteous person finds it easier to suffer hunger and starvation than become a multi-millionaire by adopting dishonest and corrupt ways and means."
