احسن الله إليكم I’m a revert and my family are not Muslim. How do I give Dawah to them and how do I learn the skills needed to give Dawah to them?

You can never be able to give dawah without seeking knowledge and putting a lot of time into it. However, one of the easiest and shortest ways as well is through your behavior and your actions. When they see how much you have improved and how you deal with them in such a nice way, that is going to affect them heavily, even more than words, while you are learning.
