I have a russian friend who is interested in islamic practises and I think he would like to know more. I have never done da'wah to nonmuslim before, what are the strategy I need to do?
My questions are as follow:
1. Any good islamic book for non muslim to read which is easy to understand and follow? Is there a pdf copy?
2. How should I approach my friend?
3. Any hadis or Quranic verse on the compulsory nature of providing information about islam to non muslim?
Hope some brothers can help.
