Sunan Ibn Majah Book 25, Hadith 35
It was
narrated from Ibn ‘Umar that when the Messenger of Allah (ﷺ)
put
his foot in the stirrup and his riding beast rose up with him, he
would say the Talbiyah from the mosque of Dhul-Hulaifah.
“The Messenger of Allah (ﷺ) addressed us and said: ‘The Talbiyah of the people of Al-Madinah begins at Dhul-Hulaifah. The Talbiyah of the people of Sham begins at Juhfah. The Talbiyah of the people of Yemen begins at Yalamlam. The Talbiyah of the people of Najd begins at Qarn. The Talbiyah of the people of the east begins at Dhat ‘Irq.’ Then he turned to face the (eastern) horizon and said: ‘O Allah, make their hearts steadfast.’”
“I was by the knees of the she-camel of the Messenger of Allah (ﷺ), at Shajarah. When it rose up with him, he said: ‘Labbaika bi ‘Umrah wa Hajjah ma’an [Here I am (O Allah) for ‘Umrah and Hajj together].’ That was during the Farewell Pilgrimage.”
