As salaamu alaikum wa Rahmat Allah wa Barakatuh akhawaati,
Ever hear the expression, "she's the envy of all her friends?" Or maybe the one, "I don't know what it is, but she's found the secret to happiness?" Well, da'awah should be about you being so unbelievably happy that the people around you want to know what the secret is. Da'awah should be everyone else wanting the "feel good" feeling that you have every single day because Allah, SWT, blessed you with this perfect deen.
If you never ate cake, and you see someone eating cake and looking miserable or sickened, will you think cake is delicious and something you want to eat? Many of the non-Muslims around us don't have a clear idea of what is good about Islam. If they see us complaining, miserable, or even just so, so about it, then why will they ever think it is something great? But, masha'Allah, seeing us as joyous, full of life, radiant women whose key to happiness is obedience to Allah, SWT, through Islam is a big advertising campaign. In fact, it is the biggest da'awah you could ever give.
Do you need to spout out all kinds of information to convince others that Islam brings about perfect happiness and peace? No. Just let them see it in action, show them what it does for you so that they can start wanting all that "feel good." Then you may just find that they start searching for the key to happiness themselves insha'Allah.
