nikki apa i dont agree with u... it doesnt say anywhere in islam... have u ever seen anyone from iran egypt or anyne from any other country doing it????
in islam... yes it does... in ahaadeeth and in practice of the prophet and his companion.
People from Iran and Egypt are NO authority on Islam.
You can tell people of Iran and Egypt (if they do not do it) that it is okay because people from rest of the muslim world do it :)
