What is the Islamic ruling on fraternizing with a Muslim Jinn, knowing that this is for the benefit of Islam and Muslims, and is done sincerely for the sake of Allaah The Almighty?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

Fraternity is a must among all Muslims; Jinn and human beings alike, for they are all meant in the verses where Allaah The Almighty Says (what means):

The Prophet, sallallaahu ‘alayhi wa sallam, mentioned that all Muslims are brothers in Islam. [Al-Bukhari and Muslim]

There is no problem with a man fraternizing with a Jinn, provided that it does not lead to committing something prohibited or supporting it.

Allaah Knows best.
