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 ٱلۡجَٰهِلِينَ

Wa in kaana kabura 'alaika i'raaduhum fa inistata'ta an tabtaghiya nafaqan fil ardi aw sullaman fis samaaa'i fata' tiyahum bi Aaya; wa law shaaa'al laahu lajama'ahum 'alal hudaa; falaa takoonanna minal jaahileen

If their spurning is hard on thy mind, yet if thou wert able to seek a tunnel in the ground or a ladder to the skies and bring them a sign,- (what good?). If it were Allah's will, He could gather them together unto true guidance: so be not thou amongst those who are swayed by ignorance (and impatience)!
