Excerpt from 'Hajj (The Pilgrimage)':
These three days following the 'Id is called Ayyam-at-Tashriq. What do they mean? On the tenth day of Zul-Hijjah you exalted to Ibrahim's position, you got the courage 'to sacrifice your Ismail', you defeated Satan in its last base at your first attack, you offered the sacrifice, you took off your Ihram and you came out victorious from the front of Mina! Why do you have to continue fighting? There is a lesson for you - do not forget that Satan may survive even after it was defeated! Every 'revolution', no matter how successful it is, is always in danger of 'counter-revolution'.
Numb snakes may wake up and change their colors while you are happy with victory, proud of power or busy with celebration! They may pretend to be your friends in order to join you and destroy the movement from within and take over the fruits of your revolution. They will be the HEIRS to the freedom-fighters and mourners for the martyrs!
Victory should not cause you to relax! So, when you have overcome Mina, do not let your hands off your arms. You have forced Satan out of your door BUT HE MAY RETURN THROUGH THE WINDOW! He was defeated 'outside of you' but he may wake up 'inside of you'. He was knocked down in war, but he may gain power in peace! He perished in Mina, but he may now flourish in you!
