Mishkat al-Masabih #2601

‘Abd ar-Rahman b. Ya'mur ad-Dili told that he heard the Prophet say, “The pilgrimage is ‘Arafa. He who gets to ‘Arafa on the night of Jam' (This would suggest that one is credited with taking part in the halt at ‘Arafa if he gets there at any time before dawn on the night when the pilgrims are at al-Muzdalifa) before dawn has attained the pilgrimage. The days at Mina are three, but if anyone hurries over matters in two days he is guilty of no sin, and if anyone is late he is guilty of no sin.” Tirmidhi, Abu Dawud, Nasa'i, Ibn Majah and Darimi transmitted it, Tirmidhi saying this is a hasan sahih tradition.
