Sura 6 Aya 35

Translator	Translation
Ali Quli Qara'i	And should their aversion be hard on you, find, if you can, a tunnel into the ground, or a ladder into sky, that you may bring them a sign. Had Allah wished, He would have brought them together on guidance. So do not be one of the ignorant.
Pickthal	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.
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.
Yusufali	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)!
