All those people who keep faith in Sanatan Dharma, believe Lord Hanuman to be the troubleshooter, and Shani Dev as the God who punishes the wrong. Both these Gods have a close connection with Lord Shiva. While Lord Hanuman is the avatar of Lord Shiva, Shani Dev received Lord Shiva’s powers after intense meditation.  Moreover, those who worship Lord Shiva are automatically blessed by Shani Dev.

Apart from these things about both these Gods, there are certain things highlighted in the Shastras, which reveal the powers, characters as well as similarities and differences between these two Gods.
