AL AN'AAM — Ayat 35

وَإِن كَانَ كَبُرَ عَلَيْكَ إِعْرَاضُهُمْ فَإِنِ اسْتَطَعْتَ أَن تَبْتَغِيَ نَفَقًا فِي الأَرْضِ أَوْ سُلَّمًا فِي السَّمَاء فَتَأْتِيَهُم بِآيَةٍ وَلَوْ شَاء اللّهُ لَجَمَعَهُمْ عَلَى الْهُدَى فَلاَ تَكُونَنَّ مِنَ الْجَاهِلِينَ

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 Allah had willed, He would have united them upon guidance. So never be of the ignorant.
