No problem in doing so as long as the graves won’t be desecrated. Give it to both your grandparents or to one of them is acceptable.

In Pakistan I wanted to make a handpump water. It will be in a grave yard where people can use it for graves and for themselves as poor people live near there and they can use if for there own household aswell. Is this permissible. My grandparents have passed away can I name this pump for both of them or is it for one person only, if it is both name both will get reward

I’ve heard it’s good to start your day by giving sadaqah, I’m a girl and cannot go outside and start my day by doing so. Instead, I’ve a money box in which every morning I put some money and at the end of the month, I give that money to some needy. Will it be accepted as sadaqah for each day, if I just keep it in money box and give it away at the end of the month.
