What is the ruling on adding "in Paradise" to the supplication: "O Allah, grant him the praised station You promised him"?

The addition of "in Paradise" to the supplication after the Adhan has no basis. The supplication ends with the words: "and raise him to the praised station which You promised him, for You never fail in Your promise."

It is recommended for the listener, when the Mu'adhdhin says: "I bear witness that there is no god but Allah, I bear witness that Muhammad is the Messenger of Allah," to repeat the same, and then add: "I am pleased with Allah as my Lord, with Islam as my religion, and with Muhammad as my Messenger." Whoever says this will have their sins forgiven.
