it is not wrong for a non-muslim to discussing to us about Islam
and it is also not wrong for him to say Allah, Duniawi, Ukhrawi
maybe he is not intend to seduce us to follow his religion,
but only to make us thinking how a non-muslim can be really love the beauty of Islam,
despite us, who does not really have the courage to love Islam beautifully
if he believes in it, just hope one day, he will be converted. InsyaAllah (:
right me if i'm wrong. Wallahualam.
btw, i have asked the ustazah for this.
