Zakaat

Assalamualaikum warahmatullahi wabatakatuh.

(Please help me on this issue on email only. )
I recently had to go for surgery in India and family, friends and strangers on social media helped me out with financial aid in order to undergo the treatment and surgery required for my health. I am now back to mauritius alhamdulillah, with my surgery being successful.
There is a small amount of money that is left from the donations (from non-believers)/zakaat (from believers). Am i allowed to keep this money as personal property cause this money i never personally asked for it. My friend was the one who took all my information and posted it on social media then people were willingly collecting money to send to me.
Also, should i remove zakaat from this money?
INSHAALLAH you help me out on this matter.
Jazakallah.

Aslm I need a help on zakaat.for the first time i will do zakaat as a couple. Can you advice me how should i proceed. I have a savings of 82000rs and a bank loan of 350000. My wife has a savings of 50000rs and a bank loan of 450000rs. We have gold jeweleries of 61grams and silver of 4.83 grams. Kindly advice me how much should i do for zakaat. Thank you for consideration.

Asssalamualaikum,
Please may we know the reason for the increase in nisaab and zakaat on 18/20 carat gold has increased compared to last year,
But the fidya is same as last year.
Jazakumullah
