The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 2968
'Ata' reported from Ibn Abbas (Allah be pleased with them): Allah's Messenger (may peace be upon him) sent me from Muzdalifa along with his luggage (in the very early part of @he dawn). I (Ibn Juraij, one of the narrators) said (to 'Ati'): Has this (news) reached you that Ibn 'Abbas (Allah be pleased with them) had said:" He (Allah's Messenger) had sent me in the latter part of the night"? Thereupon he said: No, it was the dawn. I (again) said to him: (Did you hear) Ibn 'Abbas (Allah be pleased with them) having said this (too):" We stoned al-Jamra before the dawn prayer"? So where did he observe the dawn prayer? He said: No. But he said only so much (as described above).
