Mishkat al-Masabih

Abul Baddah b. ‘Asim b. ‘Adi said on his father’s authority that God’s messenger gave licence to herdsmen of camels not to pass the night at Mina and throw pebbles on the day of sacrifice, then combine two days’ throwing after the day of sacrifice and throw the pebbles on one of them. Malik, Tirmidhi and Nasa’i transmitted it, Tirmidhi saying this is a sahih tradition.
