Shaykh Ibn Baaz:
The Muslims help their brothers among the jinn to obey Allaah and His Messenger just as they help their human brothers. Humans may help them in some matters without realizing it. They may help them to obey Allaah and His Messenger by teaching and reminding other humans, for the jinn may attend the lessons of humans in the mosques and elsewhere and benefit from them. Humans may also hear some things from the jinn which benefit them; they may wake them up to pray or draw their attention to things which may benefit them or harm them. All of this happens even though the jinn do not make themselves visible to humans. A jinn may make himself visible to some people when pointing them towards something good or something evil. This may happen, although it is rare. Usually they do not appear to humans, although their voices may be heard on some occasions when they wake a person for prayer or tell him of some things. In conclusion, the believing jinn help the believers even though the believers may not realize it, and they love everything good for them.
They may attend lessons, and they love to listen to the Quraan and knowledge, as stated above. The believers among the jinn attend the lessons of humans, at some times and in some lands, and they benefit from the lessons of humans. All of this happens and is well known. This has been clearly stated by many of the scholars whom the jinn contacted and asked about some issues; they told them that they had attended their lessons. All of this is well-known, and Allaah is the One Whose help we seek.
