All perfect praise be to Allaah, the Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
Please note first that Ihraam refers to the intention for entering the rite. Therefore, there is no harm if a violation is committed before entering it, because no Ihraam has really been made. Also, wearing the clothes of Ihraam does not in and of itself put one in the state of Ihraam.
However, if the violation is committed after making the intention of entering the rite, then a Fidyah (expiation) must be fulfilled.
