Hadees No.124
Narrated `Abdullah bin `Ammar: I saw the Prophet near the Jamra and the people were asking him questions (about religious problems). A man asked, "O Allah's Apostle! I have slaughtered the Hadi (animal) before doing the Rami." The Prophet replied, "Do the Rami (now) and there is no harm." Another person asked, "O Allah's Apostle! I got my head shaved before slaughtering the animal." The Prophet replied, "Do the slaughtering (now) and there is no harm." So on that day, when the Prophet was asked about anything as regards the ceremonies of Hajj performed before or after its due time his reply was, "Do it (now) and there is no harm."

The Prophet then said, "And they ask you (O Muhammad) concerning the spirit --Say: The spirit -- its knowledge is with my Lord. And of knowledge you (mankind) have been given only a little)." (17.85)

I would have dismantled the Ka`ba and would have made two doors in it; one for entrance and the other for exit." Later on Ibn Az-Zubair did the same
