يَا أَبَتِ لاَا تَعْبُدِ الشَّيْطَانَ
...
O my father! Worship not Shaytan.
This is means, "Do not obey him by worshipping these idols. He invites to this (idolatry) and he is pleased with it."
This is as Allah says,
أَلَمْ أَعْهَدْ إِلَيْكُمْ يبَنِى ءَادَمَ أَن لاَّ تَعْبُدُواْ الشَّيطَـنَ إِنَّهُ لَكُمْ عَدُوٌّ مُّبِينٌ
Did I not command you, O Children of Adam, that you should not worship Shaytan. Verily, he is a plain enemy to you. (36:60)
Allah also says,
إِن يَدْعُونَ مِن دُونِهِ إِلاَّ إِنَـثاً وَإِن يَدْعُونَ إِلاَّ شَيْطَـناً مَّرِيداً
They invoke nothing but females (idols) besides Him (Allah), and they invoke nothing but Shaytan, a persistent rebel! (4:117)
Concerning Allah's statement,
...
إِنَّ الشَّيْطَانَ
كَانَ لِلرَّحْمَنِ عَصِيًّا
Verily, Shaytan has been a rebel against the Most Gracious.
This means obstinate and too arrogant to obey his Lord. Therefore, Allah expelled him and made him an outcast. Therefore, "do not follow him or you will become like him. "
