Al-Furqan - 25:33

وَلَا يَأْتُونَكَ بِمَثَلٍ إِلَّا جِئْنَاكَ بِالْحَقِّ وَأَحْسَنَ تَفْسِيرًا
[25:33]
And they shall not bring to you any argument, but We have brought to you (one) with truth and best in significance.
And no question do they bring to thee but We reveal to thee the truth and the best explanation (thereof).
And they bring thee no similitude but We bring thee the Truth (as against it), and better (than their similitude) as argument.
