وَاِنْ كَانَ كَبُرَ عَلَیْكَ اِعْرَاضُهُمْ فَاِنِ اسْتَطَعْتَ اَنْ تَبْتَغِیَ نَفَقًا فِی الْاَرْضِ اَوْ سُلَّمًا فِی السَّمَآءِ فَتَاْتِیَهُمْ بِاٰیَةٍ ؕ وَلَوْ شَآءَ اللّٰهُ لَجَمَعَهُمْ عَلَی الْهُدٰی فَلَا تَكُوْنَنَّ مِنَ الْجٰهِلِیْنَ ۟

Saheeh International
And if their evasion is difficult for you, then if you are able to seek a tunnel into the earth or a stairway into the sky to bring them a sign, [then do so]. But if Allāh had willed, He would have united them upon guidance. So never be of the ignorant.
Al-Mukhtasar fi Tafsir
If their denial and turning away from the truth you have brought is difficult for you, O Messenger, then see if you can find a tunnel into the ground or a ladder into the sky so that you may bring them more proof in addition to what I have already given you. If Allah willed to guide them to the guidance that you brought, He would have done so. However, He has not willed this because of His wisdom. So do not be among those who are ignorant of this and lose yourself in regret over their denial.
