A brother who is upon Ahlul Sunnah Wal Jamah is interested in proposing to me.MashAllah his Aqeedah is correct, he is practicing and goes to pray Fajr at the masajid etc. However, his family are from the Barelvi sect.The brother has informed me that he is trying his best to give his family dawah.I want my husbands family to be upon the correct aqeedah because my children will be around them when they are older inshAllah. I want to talk to them about the deen without having any conflicting debates etc. (I will not be living with the in laws if this marriage goes forward inshAllah because there are non-mahrams in the house). What would you encourage me to do in this situation?
