Al-Qasas 28:50
فَإِن لَّمْ يَسْتَجِيبُوا۟ لَكَ فَٱعْلَمْ أَنَّمَا يَتَّبِعُونَ أَهْوَآءَهُمْ ۚ وَمَنْ أَضَلُّ مِمَّنِ ٱتَّبَعَ هَوَىٰهُ بِغَيْرِ هُدًى مِّنَ ٱللَّهِ ۚ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّـٰلِمِينَ
“But if they do not respond to you - then know that they only follow their [own] desires. And who is more astray than one who follows his desire without guidance from Allāh? Indeed, Allāh does not guide the wrongdoing people.”
Saheeh International
Essence
When people refuse a fair test, the evidence was never the problem; no one is more lost than one following desire without Allah's guidance.
A reflection
They were offered the test, and declined it
Read the ayah before this one, because this ayah is its verdict.
The Makkans had dismissed the Torah and the Quran together as 'two works of magic backing each other up'. The Prophet ﷺ was told to answer with a remarkable offer. Bring a book from Allah that guides better than these two, and I will follow it.
That is the most generous terms an arguer can give. He did not say: accept mine. He said: show me something better, and I will be the one who changes. He even put his own following on the table.
Then comes this ayah. Fa-in lam yastajībū laka: if they do not answer you, fa-ʿlam, then know. Know what? That they only follow their desires. The commentaries draw the line plainly. If they had any real argument, they would have brought it. Their silence is the evidence.
Picture a town councillor at a heated public meeting about a new school. Residents shout that the site is wrong. She says: name a better site, and I will back it at the next vote. Weeks pass. No site is named. At the next meeting the objection has moved to traffic, then to noise, then to the colour of the bricks.
She now knows something she could not know before the offer. The objection was never about the site.
This is strategy, not only theology. A fair test separates two kinds of disagreement. One is honest: show me, and I will move. The other is desire wearing an argument's clothes, and no evidence will ever be enough for it.
The ayah frees the Prophet ﷺ from an endless debate. Once the test has been refused, the problem is diagnosed. Arguing the evidence again would treat a heart problem as a reading problem.
Try this in your own disagreements. Make the honest offer: what would change your mind? If the answer is 'nothing', you have learned what you are dealing with. You can stop pleading and keep your peace.
