How can I make my devil companion obey me and embrace Islam?

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.

Everyone’s devil companion is a disbeliever who cannot obey his human companion for good, nor submit to him. The sound opinion is that the devil companion of the Prophet, sallallaahu ‘alayhi wa sallam, did not revert to Islam, rather he submitted to and obeyed the Prophet, sallallaahu ‘alayhi wa sallam.

You can weaken his schemes and influence on you by frequently remembering and mentioning Allaah and through supplication and recitation of the Quran, observing a state of purification, doing good deeds and refraining from prohibited deeds. The nearer a person is to Allaah, the weaker his devil companion’s influence is. Allaah the Almighty Says (what means): {And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a companion.} [Quran 43:36]

Allaah Knows best.
