Surah Taha Tafseer

فَأَخْرَجَ لَهُمْ عِجْلًأ جَسَدًا لَهُ خُوَارٌ

"...that was what As-Samiri suggested." Then he took out (of the fire) for them (a statue of) a calf which was mooing.

فَقَالُوا هَذَا إِلَهُكُمْ وَإِلَهُ مُوسَى

They said:"This is your god, and the god of Musa."

Muhammad bin Ishaq reported that Ibn Abbas said,

"So they became religiously devoted to it (the calf) and they loved it with a love that they had never loved anything else with before."

Allah then says,

فَنَسِيَ

but he had forgotten.

This means that he abandoned what he was following of the religion of Islam. This is referring to As-Samiri.

Allah says in refuting them and rebuking them, and also explaining to them their folly and foolishness in that which they had done
