(Az-Zukhuruf) 43 : 62
وَلَا يَصُدَّنَّكُمُ الشَّيْطَانُ ۖ إِنَّهُ لَكُمْ عَدُوٌّ مُبِينٌ
And let not Satan obstruct you; indeed, he is a manifest enemy to you.
Satan obstructs mankind from Adhikr, which is the only Path to the Lord, as explained in verses 1: 5 and 6: 153. See explanation 15: 41-44; 36: 59-62; and 38: 82-83.
