That includes the head.
Allah's Apostle stopped (for a while near the Jimar) at Mina during his last Hajj for the people and they were asking him questions. A man came and said, "I forgot and got my head shaved before slaughtering the Hadi (sacrificing animal)." The Prophet said, "There is no harm, go and do the slaughtering now." Then another person came and said, "I forgot and slaughtered (the camel) before Rami (throwing of the pebbles) at the Jamra." The Prophet said, "Do the Rami now and there is no harm."Today, however, many Jihadists claim that in order to appear transparent to the Infidels (us), shaving is not necessary. This is from the "Elders" who would never perform any kind of operation - only tell others to do it.Al-Bukhari, a ninth-century Muslim scholar who spent years collecting hadith, quotes the prophet as saying "May Allah bless those who shaved" during the Hajj (pilgrimage); and the Quran states that "ye shall enter the Sacred Mosque, if Allah wills, with minds secure, heads shaved, hair cut short, and without fear."
