Maliks Muwatta Book 20, Hadith Number 227.

Section : Indulgence with Respect to Stoning the Jamras.

Yahya related to me from Malik from Abdullah ibn Abi Bakr ibn Hazm from his father that Abu’l-Baddah ibn Asim ibn Adi told him from his father that the Messenger of Allah, may Allah bless him and grant him peace, allowed the camel-herders to spend the night outside of Mina, and they threw the stones (once) on the day of sacrifice, and (once) for the following day and the day after that, and (once) on the day when they left Mina.
