وَأَلْقِ مَا فِى يَمِينِكَ تَلْقَفْ مَا صَنَعُوٓا۟ ۖ إِنَّمَا صَنَعُوا۟ كَيْدُ سَٰحِرٍۢ ۖ وَلَا يُفْلِحُ ٱلسَّاحِرُ حَيْثُ أَتَىٰ
Throw that which is in thy right hand! It will eat up that which they have made. Lo! that which they have made is but a wizard's artifice, and a wizard shall not be successful to whatever point (of skill) he may attain.
