(An-Naml) 27 : 69
قُلْ سِيرُوا فِي الْأَرْضِ فَانْظُرُوا كَيْفَ كَانَ عَاقِبَةُ الْمُجْرِمِينَ
You say: "You travel through the land and observe how the consequence of the Mujrims was".
Doomsday will occur when no believer testifying Adhikr is there and when other people belonging to Messenger’s community such as Jains, Buddhists, Hindus, Jews, and Christians become wrongdoers and transgressors like the Arabic Quran reading Fujjar. See explanation 7: 84; 12: 109 and 22: 45-46.
