Husband seeing to the medical expenses of his wife

Q: What we know as Muslims that according to shariah man is responsible for the economic needs of his wife, but I have heard that economic responsibilities as per shariah do not include wife’s medical expenses. 

If such is the case, when in an Islamic family setup a woman is responsible to manage the house and look after her children she will have no time to earn her own income. Knowing about these circumstances when woman has no independent income because she has no employment as she was looking after the house which she is expected to do as a Muslim woman then why isn’t her husband obligated to finance her medical needs?

Is being born on a certain day a sign of bad luck?

Q: As per Hadith no. 7054 narrated in Sahih Muslim "Allah, the Exalted and Glorious, created the clay on Saturday and He created the mountains on Sunday and He created the trees on Monday and He created the things entailing labor (or hardship/displeasure) on Tuesday and He created light on Wednesday and He caused the animals to spread on Thursday and He created Adam (peace be upon him) after 'Asr on Friday..." (Sahih Muslim)." 

As per this Hadith, on Tuesday things which are hated upon/unliked are created. So I want to ask, if one is born on Monday or Friday, are they considered to be lucky/blessed? Similarly, if a person who is born on Tuesday, is that person unlucky/unblessed or unliked in the sight of Allah who has to go through a hard life? 

Fidyah for a person with dementia

Q: My grandmother passed away some years ago. During the final portion of her life (approximately two years), she suffered from dementia, due to which she would be very confused as to what day it was, whether she had eaten or not, etc. At this time, she stopped performing salaah as well. My questions are: 

(1) Does fidyah need to be paid for the all salaah she did not perform during the period she suffered from dementia? 
(2) If yes, can the fidyah be paid from her estate/wealth? 
(3) If the fidyah cannot be paid from the estate, who is responsible for paying it?

Ma'zoor sleeping through an entire salaah period

Q: 

1. If the wudhu of a mazoor person (urine incontinence) sometimes, but not always, lasts through a short salaah period, namely maghrib, will he still be considered a mazoor? 

2. If he accidently sleeps through a salaah period, he will not know whether or not something exited, since movement is little during sleep, it's unlikely something exited, will he still be considered a mazoor?

Settling one's debts before giving nafl sadaqah

Q: I will be receiving about R50 000 in inheritence. 

I am married with 4 kids but my husband doesn't always provide. I work, and earn a basic salary and most often I am paying for my children's clothes or treats etc. 

I want to give 10% of my inheritance in charity, however I do have debts to pay and most of the time, my money is all finished and I can't buy myself anything. 

Is it better to give out the amount as sadqah or better to pay off my debts and my zakaat which is due and keep the rest as an emergency nest.
