Verse 35

وَإِن كَانَ كَبُرَ عَلَيْكَ إِعْرَاضُهُمْ فَإِنِ ٱسْتَطَعْتَ أَن تَبْتَغِىَ نَفَقًا فِى ٱلْأَرْضِ أَوْ سُلَّمًا فِى ٱلسَّمَآءِ فَتَأْتِيَهُم بِـَٔايَةٍ وَلَوْ شَآءَ ٱللَّهُ لَجَمَعَهُمْ عَلَى ٱلْهُدَىٰ فَلَا تَكُونَنَّ مِنَ ٱلْجَـٰهِلِينَ

And if their ignorance is too much for you to bear, know that it would not be enough even if you had the ability to tunnel through into the ground or climb a ladder into the sky then produce all kinds of signs for them. And had God willed He could have indeed guided all of them. Therefore do not be one of the ignorant ones.
