Is it true that the peacock and serpent helped satan to enter heaven?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

Al-Qurtubi stated that Wahb Ibn Al-Munabbih said: 'The devil entered Paradise in the mouth of a serpent.' This is among the stories, and interpretations that are taken from the Israelites and there is no authentic narration about it, as far as we know. As regards the peacock having helped the devil in this regard, we did not come across any evidence proving this in any religious books.

Allaah Knows best.
