In some places i saw a women jamaah praying at 2nd floor and the men 1st floor is it correct and some places also I saw a women jamaah praying distances away from men more then 10 meters. Is that also correct?
Jama'ah in second floor is OK, provided that the height is not abnormal, while if the distance is more than 1 meter between men and women, then jama'ah is not valid.
