Tafsir

The Egyptians were confident of their success and in a mood of complacency asked Sayyidna Musa (علیہ السلام) whether he would like to make the first move or whether they should initiate the contest. Sayyidna Musa (علیہ السلام) invited them to start the contest (Rather, you throw - 20:66) and there were several reasons for this. In the first place the Egyptians showed courage when they invited Sayyidna Musa (علیہ السلام) to open the battle and this offer called for an equally generous and chivalrous response. Secondly by making the offer the Egyptians showed their confidence in the outcome of the contest and implied as if they had already won it. On his side Sayyidna Musa (علیہ السلام) ، by his counter-offer, sought to convey to the Egyptians that he regarded the result of the game as a foregone conclusion in his own favour. And finally he wished to see the tricks of the Egyptians before he planned his own strategy.

So, with these preliminaries over, the Egyptians cast their staffs and ropes on the ground and it appeared to the onlookers as if they had turned into snakes and were running about.يُخَيَّلُ إِلَيْهِ مِن سِحْرِ‌هِمْ أَنَّهَا تَسْعَىٰ (Their ropes and sticks seemed to him, due to their magic, as if they were running - 20:66). The verse shows that the Egyptian magicians had cast a hypnotic spell on the onlookers to whom it appeared that the staffs and the ropes had turned into snakes and were running about on the ground, whereas in fact no such transformation had taken place.
