۞ وَقِيلَ لِلَّذِينَ ٱتَّقَوْا۟ مَاذَآ أَنزَلَ رَبُّكُمْ ۚ قَالُوا۟ خَيْرًا ۗ لِّلَّذِينَ أَحْسَنُوا۟ فِى هَٰذِهِ ٱلدُّنْيَا حَسَنَةٌ ۚ وَلَدَارُ ٱلْءَاخِرَةِ خَيْرٌ ۚ وَلَنِعْمَ دَارُ ٱلْمُتَّقِينَ

Commentary:
V. 25 above stated what disbelievers thought of the revelation sent down to the Holy Prophet. The present verse gives the opinion of the Faithful regarding the Quran in the words, They say, 'The best'. It must be remembered that the Faithful gave this testimony in favour of the Quran at Mecca where they were being bitterly persecuted for believing in it. A testimony given under such circumstances is entitled to the greatest possible respect. The Faithful were asked what they had found in the Book worth believing for which they were undergoing so much persecution, and the reply they invariably gave was that they had found it to be the Ideal Book, i.e. all that was essential for a perfect code of laws to contain was found in it or that this Book exceeded all their expectations.
The words, For those who do good, signify that a change in one’s attitude and outlook brings about a corresponding change in one’s deeds and actions. Disbelievers looked upon the Quran as a mere collection of tales, therefore they disregarded its warnings and consequently became deprived of all good. But believers looked upon it as خیر viz. the Ideal Book, so they acted upon it and thus reaped a good reward in this world and خیر i.e. the ideal reward, in the life to come.
