Sunan Ibn Majah Book 25, Hadith 142
“The Messenger of Allah (ﷺ) departed during the
Farewell
Pilgrimage in a tranquil manner, and he urged them to be
tranquil. He
told them to throw small pebbles. He hastened through
Muhassir
Valley, and said: ‘Let my nation learn its rites (of Hajj),
for I
do not know, perhaps I will not meet them again after this
year.’”
“We performed Hajj with ‘Umar bin Khattab, and when we wanted to depart from Muzdalifah, he said: ‘The idolators used to say: “May the sun rise over you, O Thabir!* So that we may begin our journey (to Mina),” and they did not depart until the sun had risen.’ So the Messenger of Allah (ﷺ) differed from them by departing before the sun rose.”
“O Bilal, calm the people down,” or “make them be quiet.” Then he said: “Allah has been very gracious to you in this Jam’ of yours. He has forgiven the wrongdoers among you because of the righteous among you, and He has given the righteous among you whatever they ask. Move on in the Name of Allah.”
