salamunalikum,

yup i think the best of the daee's are the one's who are more subtle..?

personally i think my brother is a great dawah giver (yeah yeah im a bit biased lol) he's verrry freindly, funny and charismatic...in a good way...and he never argues cos he goes it spreads the hatred...people just dont listen to u once u start to refute and argue with them..instead he tends to depart on good terms

and if some one is rly interested in islam he always humbly hands them over to some one who has more knowledge than him...personally i dont see that quality often enough!!

and thats the best way to do it..we shudnt force our religion on people, only Allah (Swt) can open their hearts and minds...we shud just be wise and act accordingly.
