Maliks Muwatta Book 20, Hadith Number 178.
Section : The Wuquf at Arafa of Someone who Misses the Hajj.
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, “Someone who does not stand at Arafa on the night of Muzdalifa before the dawn breaks has missed the hajj, and someone who stands at Arafa on the night of Muzdalifa before the dawn breaks has caught the hajj.”
