BismilLaahir Rahmaanir Raheem
If you are striving as a sincere Musilm, you don’t talk too much- about anything-and you perform good deeds as secretly as possible and you try to be as peaceful and helpful to others as you can without asking anything in return. (You also take your pleasure in simple things, not expensive vacations and lavish living.) You prefer others over yourself and you don’t display your wealth or worldly success by accumulating the finest cars, homes and clothes. Anything else is folly and you’ll pay for it one day.
Don’t be a Muslim "activist" if all your activity is going to be outside the home. And don’t be an Islamic "terror" to your family: coming in like a whirlwind, from time-to-time, upsetting the normal schedule of everyone, even if you’re enraged by what you see your family doing. Because if your family is doing things that are not good Islamically, then where were you all those years when those things were being built up in their minds and habits.
A series of lectures or thrashings on your part won’t change their attitudes. Only when others see Islam make a meaningful change in your life will they be willing to try the same.
That is the real Daawah to the family, that is the only message that they will listen to and the only way to make Islam survive in your family tree. Think about it, apply it and feel the success of your daawah.
May ALLAH aid us through our effort to help ourselves and our families. AMIN
