Sahih Muslim
The Book of Pilgrimage (Kitab Al-Hajj)
Book Number: 007 / Hadith Number: 2786
A'isha (Allah be pleased with her) reported that the Apostle of Allah (may peace be upon him) came out (for Pilgrimage) on The 4th or 5th of Dbu'l Hjjja. The rest of the hadith is the same, but he (the narrator) made no mention of the doubt of Hakam about his (the Prophet's) words:" They were reluctant."
