(Banu Israel in the specified time created chaos and disorder in the lands, so God burdened them with difficult religious duties and rulings, some of these rulings being sins that have no repentance).

Narrated Atta bin Abi Rabah: Al-Esser can be a reference to the curse that God gave upon Banu Israel for their wrong-doings in the lands, which was transforming them into actual apes and pigs.
