This is an important & necessary question we all come across like watching new converts to Islam or Islamic lecture videos
We Men must avoid
staring or looking at her beauty etc etc
or admire her voice. If such a thing comes to your mind put off.
Like Bro @
Serenity says if there is fear of fitna we should avoid it and though we watch with our intention to know & boost our eeman through her inspirational incidents events to islam , we better avoid the haram thing like looking at her face etc (
though Hadith had allowed the FIRST GLANCE (
imho if necessary just to know WHO it is ? But Not to know is she beautiful etc except you are searching for nikkah - only the first glance and NOT for minutes imo or the second glance )
Also its better for the Usual Female lecturers of Islam to come with a Niqab or do not expose their faces in Videos where every one can look at them . As we see Aisha :ra: giving lectures ONLY behind the curtain to the ghair maghram Sahabas though she was the Mother of Believers.
