Proceeding to Arafah
So after the sun rises on the Day of ĎArafah (10th Dhul-Hijjah) - he moves off towards ĎArafah (a large plain to the south-east of Mecca), while reciting talbiyah of takbir - as both of these were practiced by the Companions of the Prophet while making Hajj with him - and he did not criticize either (those reciting talbiyah of those reciting takbir.) 
Then he stops at Namirah  - and it is a place near to ĎArafah but not forming part of it - and he remains there until noon.
So When the sun passes its zenith he moves to ĎUranah and settles there,  and it is next to ĎArafah - and here the Imam should give an appropriate Khutbah to the people.
Then he prays with the people Dhuhr and ĎAsr shortening and combining them in the time of the Dhuhr prayer.
And one adhan is given and two iqamahs.
And he does not pray anything between the two prayers. 
And he who is not able to pray along with the Imam - then he prays them in the same way on his own - or with those in similar situation around him. 
Standing In ĎArafah
Then he goes off to ĎArafah and if able stands upon the rocks beneath the Mount of Mercy (Jabal ur-Rahmah) and if not then all of ĎArafah is place of standing.
And he stands facing the Qiblah, raising his hands making du'a and reciting talbiyah.
And he recites much ĎLa ilaha illallah' as it is the best du'a on the Day of ĎArafah as the Prophet said: The best thing that I and the Prophets have said on the evening of ĎArafah is La ilaha illallahu wahdahu la sharika lahu lahul mulku wa lahul hamdu wa huwa Ďala kulli shay'in qadir. 
And if he adds in the talbiyah occasionally (all good is the good of the Hereafter) then that is permissible.  Innamaal Khairu Khairul Aakhirati.
And it is Sunnah for the one standing in ĎArafah not to fast that day.
And he remains in that state, remembering Allah reciting talbiyah, making du'a as he wishes - hoping from Allah that He will make him one of those whom He boasts of (those whom He frees from Fire) to the Angels as occurs in the hadith: ĒThere is no day on which Allah frees more of His slaves from Fire than the Day of ĎArafah, and He verily draws near then boasts of them before the angles, saying: 'What do they seek?' ď  and in another hadith: ďVerily Allah boasts of the people of ĎArafah before the people of heaven (the angels), saying: ĎLook to my servants who have come to Me disheveled and dusty.'Ē  and he remains in that state until the sun sets.
So when the sun has set he leaves ĎArafah for Muzdalifah - going with calmness and tranquility, not jostling or pushing the people with himself or his riding beast or his vehicle, rather whenever he finds room then he goes faster.
And when reaching Muzdalifah he gives adhan and iqamah then prays the three rak'ahs of Maghrib, then gives iqamah and prays ĎIsha' - shortening it - and joining the two prayers.
And if he separates the two prayers for some necessity then there is no harm in that. 
And he does not pray anything between them or after ĎIsha'. 
Then he sleeps until Fajr.
Then when the dawn first appears he prays Fajr in the first part of its time with adhan and iqamah.
