Verily, those who turn away from Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc. by attacking, distorting and denying them), are not hidden from Us. Is he who is cast into the Fire better or he who comes secure on the Day of Resurrection? Do what you will. Verily! He is All-Seer of what you do (this is a severe threat to the disbelievers).
