Giving something in sadaqah instead of throwing it away

Q: I was for Umrah in Madina and had around 15 atar bottles which I didn't like and thought of giving to someone instead of throwing them away. I found a street vendor and gave it to him. He also gave me one atar and miswak as part of gesture.

1. Is it ok to give from my side? Will I be rewarded?

2. Can I take it from him? I don't know his niyat of giving it to me, probably he mentioned this is from my side as you have given this to me.

3. Later, I gave both atar and miswak adding some money to a poor person. Is it correct?

Poor person using interest money to pay off a loan

Q: I have a credit card loan which I need to pay immediately. For several months I am trying to pay it but I failed. I don't have sufficient money to pay it. But I have a bank deposit from where interest money is automatically generated. I have no other source to pay it other than this interest money.

Previously I did not use this interest money due to Islamic reasons. But now I am in an emergency situation as if I fail to pay my debt, it will generate interest. Kindly help me and show me the correct path. May I use this interest money to pay my debt and seek forgiveness to the Almighty Allah?

Wearing a taweez

Q: Is it permissible to wear taweez for children and adults? Ayat ul kursi, the quls.

And for babies the dua: Aoothoo bi Kalima til la hit ta mah ti min kuli shay taanin wa haa ma tin wa min kulli ay nin la mah tin.

Also is it permissible to wear a necklace for women with ayaat ul kursi engraved on it?

If it is permissible, I know the necklace has to be removed before entering the toilet area. But the taweez being covered in a cloth, will it also have to be remove?

Following the rules and regulations of a company one works for

Q: Is there any rules and regulations about not working according to an organization's standards?

For example, I work in an organization and my job is to give bonus amount to others based on their work. There is a chart by the organization about how much bonus should be provided according to the work. But if I don't follow it and give a bonus not according to them, will it be ok or not?
