Is it permissible to place animals in cages in zoos and purchase a ticket to visit them?

It is permissible to place animals in cages and invite people to view them for a fee, based on the action of the Prophet, peace and blessings be upon him, with the nightingale, but with conditions:

1. Providing them with food, drink, and healthcare.

2. Not harming them, overworking them, mutilating them, or branding their faces.

3. Not separating a mother from her offspring except out of necessity.

4. Not being extravagant with money for their upkeep and raising.

5. Taking care to place barriers between harmful animals and visitors.

It is recommended to provide information about each animal so that visitors may reflect on the power of Allah.
