An article named 'Hajj: Tips and Reflections' which I read from the site: IslamiCity (http://www.islamicity.com/)

In this, the author relates from his own experience in the year 2001 that during your time in Makkah: ?6) Most tours when departing Mt Arafat, travel directly to Mena to throw Al-Jamrah Alkubrah, others stop briefly at Al-Musdalifah then continue to Mena while others spend the night or part of it at Al-Musdalifah and then continue to Mena. If at all possible, after leaving Mt Arafat, spend the night at Al Muzdalifah, pray Fajr, then go directly to the Kaba and 1-perform Tawaf Al Ifadah. 2-shave/cut your hair, 3-pay for the slaughter, if applicable, 4-change your Ihram clothes and wait for the evening, 5- to throw Al Jamrah Al Kubrah. This is a good way to avoid the crowd. What I wanted to know was that is it right to take off your Ihram and then do Rammi and 'qurbani' (and also 'Tawaf Al Wada' afterwards) ; as mentioned in this article. Please give some reference from Hadith. Jazakallah Khairun.
