Regarding your question, we should avoid as much as we can talking with opositive gender, how in our daily life, as well here on TTI. Alhamdulilah we are alowed to talk about Islaam, like here on TTI we are taking and disscusing about Islaam or other issues on public threads. But we should avoid freerly and unnecerry talking with opostive gender.
Dear brother, it is fine that you are talking with colegs- sisters from your class, but it should be limited only for neccesery talking. I am sure you are good Muslim dear brother,and may Alah keep you always like that. ameen:tti_sister:
