Those women with whom nikaah is permissible

Marrying a jinn

Q: I would like to know we as Muslims are allowed four wives. Could I marry a jinn woman? What is your opinion on this? My reason for asking such a question is I am frequented by female jinn at night. Now I can't stop thinking of them.

Getting married to a girl who is not baaligh

Q: We learn that Nabi (Sallallahu Alayhi Wasallam) married Hazrath Ayesha (Radiyallahu Anha) at a very young age. Is this something that was limited to Nabi (Sallallahu Alayhi Wasallam) or that era, or is it permissible for us to also make Nikah with a girl who is not baaligh? We also learn that Hazrath Ayesha (Radiyallahu Anaha) only went to live with Nabi (Sallallahu Alayhi Wasallam) later. Was this because Nabi (Sallallahu Alayhi Wasallam) was waiting for Hazrath Ayesha (Radiyallahu Anha) to become baaligh before Hazrath Ayesha (Radiyallahu Anha) came to live with Nabi (Sallallahu Alayhi Wasallam)?
