Maliks Muwatta Book 43, Hadith Number 10.

Section : Inheritance of Blood-Money and Dealing Harshly in Taking It.

Malik related to me from Yahya ibn Said from Amr ibn Shuayb that a man of the Banu Mudlij called Qatada threw a sword at his son and it struck his thigh. The wound bled profusely and he died. Suraqa ibn Jusham came to Umar ibn al-Khattab and mentioned that to him Umar said to him, “At the watering place of Qudayd count one hundred and twenty camels and wait until I come to you.” When Umar ibn al-Khattab came to him, he took thirty four-year-old camels, thirty five-year-old camels, and forty pregnant camels from them. Then he said, “Where is the brother of the slain man?” He said, “Here.” He said, “Take them. The Messenger of Allah, may Allah bless him and grant him peace, said, ‘The killer gets nothing.'”

Malik said that he had heard that Said ibn al-Musayyab and Sulayman ibn Yasar were asked, “Does one deal more harshly in taking the blood-money in the sacred month?” They said, “No. But it is increased in it because of violating the month.” It was said to Said, “Does one increase for the wound as one increases for the life?” He said, “Yes.”

Malik added, “I think that they meant the same as what Umar ibn al-Khattab did with respect to the blood-money of the Mudliji when he struck his son.” (i.e. giving 120 camels instead of 100).
