وَاِنۡ كَانَ كَبُرَ عَلَيۡكَ اِعۡرَاضُهُمۡ فَاِنِ اسۡتَطَعۡتَ اَنۡ تَبۡتَغِىَ نَفَقًا فِى الۡاَرۡضِ اَوۡ سُلَّمًا فِى السَّمَآءِ فَتَاۡتِيَهُمۡ بِاٰيَةٍ ؕ وَلَوۡ شَآءَ اللّٰهُ لَجَمَعَهُمۡ عَلَى الۡهُدٰى فَلَا تَكُوۡنَنَّ مِنَ الۡجٰهِلِيۡنَ (الأنعام :35)
Wain kana kabura 'alayka i'raduhum faini istata'ta an tabtaghiya nafaqan fee alardi aw sullaman fee alssamai fatatiyahum biayatin walaw shaa Allahu lajama'ahum 'ala alhuda fala takoonanna mina aljahileena
Sahih 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 Allah had willed, He would have united them upon guidance. So never be of the ignorant.
وَلَوۡلَاۤ اَنۡ يَّكُوۡنَ النَّاسُ اُمَّةً وَّاحِدَةً لَّجَـعَلۡنَا لِمَنۡ يَّكۡفُرُ بِالرَّحۡمٰنِ لِبُيُوۡتِهِمۡ سُقُفًا مِّنۡ فِضَّةٍ وَّمَعَارِجَ عَلَيۡهَا يَظۡهَرُوۡنَۙ(الزخرف :33)
Walawla an yakoona alnnasu ommatan wahidatan laja'alna liman yakfuru bialrrahmani libuyootihim suqufan min fiddatin wama'arija 'alayha yathharoona
Sahih International:
And if it were not that the people would become one community [of disbelievers], We would have made for those who disbelieve in the Most Merciful - for their houses - ceilings and stairways of silver upon which to mount
اَمۡ لَهُمۡ سُلَّمٌ يَّسۡتَمِعُوۡنَ فِيۡهِ ۚ فَلۡيَاۡتِ مُسۡتَمِعُهُمۡ بِسُلۡطٰنٍ مُّبِيۡنٍؕ(الطور :38)
Am lahum sullamun yastami'oona feehi falyati mustami'uhum bisultanin mubeenin
Sahih International:
Or have they a stairway [into the heaven] upon which they listen? Then let their listener produce a clear authority.
