وَإِنَّهُ لَذِكْرٌ لَّكَ وَلِقَوْمِكَ (And certainly this Qur'an is a word of honor for you and your people... 43:44) The original word used in the text is dhikr which here means 'good name' or 'fame'. The verse means that the Noble Qur'an is a matter of great honour and good fame for the Holy Prophet t and his people. Imam Razi has concluded from this verse that good fame is a desirable thing, because Allah Ta ala has stated this as a matter of favor and that is why Sayyidna Ibrahim' (علیہ السلام) had supplicated:
(And destine for me a truthful description among the next generations) (26:84)
But one must keep in mind that the good fame is praiseworthy only when it is received as an automatic result of virtuous deeds, but when virtuous deeds are done for the sake of good fame, then it becomes riya' (ostentation) which not only nullifies all the rewards of good deeds, but also renders one guilty of a major sin.
In this verse the words 'your people' have been taken by some exegetes to mean the tribe of Quraish only, thereby proving the superiority of Quraish, whereas ` Allamah Qurtubi says that, according to the correct view, these words refer to the whole Ummah of the Holy Prophet ﷺ ، irrespective of color or race, and the Noble Qur'an is a matter of honor and good fame for the whole Ummah. (Qurtubi)
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 39–44
Man’s turning away from good advice means his rejection of reality. Divine reality comes before him with undeniable, reasoned arguments. However, in order to protect his interests, he ignores it. One who does so makes false statements against it in order to justify his stand. This is when Satan has the opportunity to get the better of him and turn his mind in the wrong direction. Keeping the man busy with false justifications, Satan goes on assuring him that he is on the right path. The spell of deceit is broken only when the man meets his death and is produced before God for the final reckoning. In this world, man is wont to readily make friends with anyone who supports his falsehood, but in the Hereafter, he will curse all such companions. He will then want them to stay so far away from him that he should be able neither to see their faces nor hear their voices.
