Yusuf Ali
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)!

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.

Shakir
And if their turning away is hard on you, then if you can seek an opening (to go down) into the earth or a ladder (to ascend up) to heaven so that you should bring them a sign and if Allah had pleased He would certainly have gathered them all on guidance, therefore be not of the ignorant.

Pickthall
And if their aversion is grievous unto thee, then, if thou canst, seek a way down into the earth or a ladder unto the sky that thou mayst bring unto them a portent (to convince them all)! - If Allah willed, He could have brought them all together to the guidance - So be not thou among the foolish ones.

محمد جالندھری
اور اگر ان کی روگردانی تم پر شاق گزرتی ہے تو اگر طاقت ہو تو زمین میں کوئی سرنگ ڈھونڈ نکالو یا آسمان میں سیڑھی (تلاش کرو) پھر ان کے پاس کوئی معجزہ لاؤ۔ اور اگر خدا چاہتا تو سب کو ہدایت پر جمع کردیتا پس تم ہرگز نادانوں میں نہ ہونا
