It was narrated from Al Baddah bin ‘Asim bin ‘Adiyy from his father, that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم granted a concession to some camel herders, allowing them to not stay overnight in Mina, and allowing them to stone the Jimár on the Day of Sacrifice, then to combine the stoning of two days after the sacrifice, so that they could do it on one of the two days. (Sahih)
