So these fuqha are basing their argument on one hadith (standing up) and ignoring all the other ahadith about sitting down as well as the famous hadith of Aisha’ to conclude that both are fine.
And their reason “to avoid impurity” and “to be able to see if anybody is there”…hello! people don’t go to the fields anymore to relieve themselves.
Do you really buy this? And who are these “fuqhas”?
