Does talaaq take place through the husband complaining?

Q: My husband complained to my mother that"your daughter is not giving me time" out of misunderstanding. He said I cant tolerate this situation and I am fed up with this situation. My mother told him to have patience then he replied that "I am sorry I can not tolerate this." He didnt use any word of divorce at all. It was just he was complaining. He swore to Allah his only intention was to talk to me. But I am confused that can these words constitute divorce?

Taking back zakaat money

Q: I gave my zakaat to a lady to purchase a blender to start her business after she informed me that she was eligible to collect Zakaat. Later I found out from her that she used the money for unnecessary things and had no intention of furthering her business. She still has the balance of the money. Do I take the balance and give it to someone who is deserving of Zakaat?

Water on the toilet seat

Q: I really need some advice on the principle of cleanliness. I use to see water sometimes go underneath the toilet seat and then onto the floor of the toilet. However, before I never realised this and carried on wearing sandals from the toilet to the bathroom, and sometimes walked in the toilet barefoot.

1) Does this mean the toilet floor and bathroom floor are najas because of water being transferred? Also, ever since buying a new toilet seat I have seen that this one doesn't allow water to fall from beneath the toilet seat onto the floor but my brother goes in barefoot and walks into the bathroom like that. When I usually clean the toilet seat I see urine underneath, which most likely means the water on the floor was najas all this time. I don't know if my toilet was mopped before or not, but

2) does this mean najas water has been tread on and transferred by foot everywhere. Also, I wash the sandals every time I see them flipped face downwards on the bathroom floor, even though this can be time consuming. I use to suffer from a lot of waswasa many years ago and pray to never go there again. I really need some clarity on this matter because I worry I might over do cleaning things again. I might be overthinking this because my mum also walks into the bathroom barefoot sometimes and even when the floor is wet, which makes me think I might be losing my mind again, but I don't ask her anything about it Incase she thinks I've lost my mind again.

3) If my family walk barefoot on the bathroom floor and then wear a clean pair of sandals I've washed, do I have to wash them again?

4) Furthermore, do I have to wipe the toilet seat with a dry tissue and then with a wet one every time I find the lid open? Does it matter if someone before me didn't wipe the toilet seat dry after finding the toilet lid open? (Sorry for making it very long) I have owned two hoovers so far, and the old one was used in the bathroom when the floor was wet but I didn't know much about cleanliness back then. With the new one, I don't remember if I've used it on the bathroom floor when it was wet, but I am 100% sure that I've used the shorter top end of it to clean the floor when it was wet. Does this mean the whole Hoover is najas; because I don't remember if I touched other parts of it with wetness on my hand.

5) what should I do to clean the Hoover? Do I just wipe the shorter end of it and leave it at that.

Black magic

Q: Please help me. My family is suffering for the past one year. In Jan we suddenly saw a taweez at home which was certainly black magic. We are not the ones to go to some one for solution but just rely on Allah and Quran. The year has been a real tough one including my father diagnosed with cancer and two major surgeries plus lots and lots of complications plus ill health of almost all family members. But all this time we stayed patient relying on Allah and Qur'an. Now again my mother found out one more taweez in my room as I stay overseas with my husband and the room is always locked. Please help me find out the meaning of it. Please I beg of you.
