Surah Al-An'am, Verse 35

وَإِن كَانَ كَبُرَ عَلَيۡكَ إِعۡرَاضُهُمۡ فَإِنِ ٱسۡتَطَعۡتَ أَن تَبۡتَغِيَ نَفَقٗا فِي ٱلۡأَرۡضِ أَوۡ سُلَّمٗا فِي ٱلسَّمَآءِ فَتَأۡتِيَهُم بِـَٔايَةٖۚ وَلَوۡ شَآءَ ٱللَّهُ لَجَمَعَهُمۡ عَلَى ٱلۡهُدَىٰۚ فَلَا تَكُونَنَّ مِنَ ٱلۡجَٰهِلِينَ٣٥

wa-in kāna kabura ʿalayka iʿ'rāḍuhum fa-ini is'taṭaʿta an tabtaghiya nafaqan fī l-arḍi aw sullaman fī l-samāi fatatiyahum biāyatin walaw shāa l-lahu lajamaʿahum ʿalā l-hudā falā takūnanna mina l-jāhilīna

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.
