Extent of being financially stable when getting married

Q: We are always advised by Ulama to get married early but on the other hand we are also supposed to provide for our spouse and most of the boys get financially stable or land a job only up until their mid to late 20s (atleast where I am from).

I have also heard that it is the duty of parents to get their child married on becoming baaligh.

My question is, how can we acheive balance in it when it is not possible to get financially independent early but it is also necessary for a husband to provide.

For example, when I was 17, an Aalim advised me to get married at a majlis, but how can a 17 year old fulfill the right to provide?

What is the extent of financial capability and what is the role of parents here (in light of that they are told to get children married)?

Making taubah for taking an interest loan

Q: If a person, who in ignorance, took out an interest loan, thereafter realized his sin, made sincere taubah and made a promise to Allah never to take such loans again. However he still has the debt/loan to pay off and he doesn't have the full amount to settle it. Now going forward, does he still fall under the curse of Nabi (salallahu alayhi wa sallam), as he still has to pay off the loan and he will still be paying interest? Please advise whats the way to correct the situation.

Suicide in Islam

Q: What does Islam say about a person committing suicide because of black magic? I know suicide is haraam in Islam, but if the person who committed suicide was a really pious man, prayed five times a day and lived his whole life according to Islam, but in the last month of his life, he started seeing things who were telling him to take his life, not to pray and eventually he took his life, then what is his status?
