Imam Malik's Muwatta, Chapter: Hajj

Yahya related to me from Malik from Abu Bakr ibn Nafi from his father that the daughter of one of Safiyya bint Abi Ubayd's brothers was bleeding after she had given birth to a child at Muzdalifa. She and Safiyya were delayed and did not arrive at Mina until after the sun had set on the day of sacrifice. Abdullah ibn Umar told them both to stone the jamra at the time they arrived and he did not think that they owed anything. Yahya said that Malik was asked about some one who forgot to stone one of the jamras on one of the days of Mina until it was evening and he said, "He should throw the stones at whatever time of day or night he remembers, just as he would pray the prayer if he forgot it and then remembered it at any time of day or night. If he remembers (that he has not done the stoning) after he has returned to Makka, or after he has left, he must sacrifice an animal."
