Man kana yureedu alAAizzata falillahi alAAizzatu jameeAAan ilayhi yasAAadu alkalimu attayyibu walAAamalu (surah Fatir: 10)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(35:10) He who seeks glory, let him know that all glory belongs to Allah alone.  *20To Him do good words go up, and righteous action uplifts them. *21 But those who contrive evil deeds, *22 a severe punishment lies in store for them, and their contriving will come to naught.

Man kaana yureedul `izzata falillaahil `izzatu jamee`aa; ilaihi yas`adul kalimut taiyibu wal`amalus saalihu yarfa`uh; wallazeena yamkuroonas sayyiaati lahum `azaabun shadeed; wa makru ulaaa`ika huwa yaboor

*20) It should be noted that whatever the chiefs of the Quraish were doing against the Holy Prophet, they were doing it for the sake of their honour and dignity. They thought that if the Holy Prophet succeeded in his mission, their greatness and glory would fade away, their influence would die out and their honour among the Arabs would be ruined. At this it is being said: "The honour that you have attained for yourselves by your disbelief in and rebellion against Allah. is a false honour, which is destined to be mined. The taste and enduring honour, which can never suffer debasement, can be attained only through service of Allah. If you turn sincerely and faithfully to Him, you will attain it; and if you turn away from Him you are bound to live an abject, wretched life. "
*21) This is the real means of attaining the honour. In the sight of Allah the false, vicious and mischievous can never rise and flourish. In His sight only such a word can rise and flourish; which is taste and pure and based on the truth, and in which a righteous creed and a correct point of view may have been expressed and presented. Then the thing which makes the pure word rise and prosper is the action which conforms to it. Wherever the word is pure but the action opposed to it, the purity of the word suffers a blemish. The mere extravagant rise of the tongue does not exalt a word: the power of the righteous action is needed to exalt and raise it high.
Here. one should also note that the Qur'an presents the righteous word and the righteous action as inter-dependent. No action can be righteous merely on the basis of its external and apparent form unless it has a righteous creed behind it. And no righteous creed can be reliable unless it is supported and confirmed by a person's action. For instance, if a person says that he regards AIlah, the One. alone as his Deity, but worships others than Allah in practical life, his action belies his word. If a person says that he regards the wine as unlawful but drinks, his mere word can neither be acceptable to the people nor deserve approval in the sight of Allah.
*22) Those who plot evil": Those who propagate false and evil words by means of cunning tricks, deceit and deceptive reasoning, and do not feel any hesitation in employing any device, however mean and depraved, to furstrate and defeat cite word of the truth.
