Praise be to Allaah.
The farewell tawaaf is the last of the actions of Hajj, so it
is not permissible to do it before any of the other rituals, because of the
hadeeth of Ibn ‘Abbaas (may Allaah be pleased with him): “The people were
commanded that the last thing they do should do is to circumambulate the
House”
And Allaah is the Source of strength. May Allaah send
blessings and peace upon our Prophet Muhammad and his family and companions.
