Muwatta Imam Malik (Riwayat Yahya)

Imam Malik, may Allah have mercy on him, said that if a person has intercourse with his wife while in the state of ihram for ‘umrah, then a sacrificial animal (hady) is obligatory upon him, and making up that ‘umrah is also obligatory. The ‘umrah that was invalidated by intercourse should be completed, and immediately after that, the make-up ‘umrah should be started. The ihram for the make-up ‘umrah should be assumed from the same place where the ihram for the invalidated ‘umrah was assumed. However, if the ihram for that ‘umrah was assumed before reaching the miqat, then assuming ihram from the miqat is sufficient.
