The word(s) "tunnel" appears 1 time(s) in 1 verse(s) in Quran in Saheeh International translation.

(1) 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.
