Q:
1. I am married, I have a sister in-law and brother in-law, they are also married. We all stay in Saudi as neighbours, so is it permissible that we three families go for umrah together in a big car provided all females are fully covered in burqa?
2. Similarly can we three families go on a picnic trip to various tourist attractions provided all females are covered in burqa but obviously the females can see the men of their family through eye opening of niqab if they don't lower their gaze but males can't. so is it permissible to travel together in this manner?
3. Another situation is if all of the three families travel in their personal car but on reaching the destination they unite,but no casual conversation is there between na mahrams of family, each family just enjoy themselves and have fun,only thing is they all go the place same day for a happiness in their personal vehicles, is it permissible to travel in this manner?
