4 verses have
truth
in Edition Clear Qur'an by Talal Itani / Al-Ankaboot (The Spider)

29:3We have tested those before them. God will surely know the truthful, and He will surely know the liars.

29:29You approach men, and cut off the way, and commit lewdness in your gatherings.” But the only response from his people was to say, “Bring upon us God’s punishment, if you are truthful.”

29:44God created the heavens and the earth with truth. Surely in that is a sign for the believers.

29:68And who does greater wrong than he who fabricates lies and attributes them to God, or calls the truth a lie when it has come to him? Is there not in Hell a dwelling for the blasphemers?
