Hazrat Saeed bin Musayyib and Sulaiman bin Yasar were asked: If someone commits murder in the sacred months (Muharram, Rajab, Dhu al-Qa'dah, and Dhu al-Hijjah), will you make the blood money stricter? They replied: No, rather we will increase it, due to the sanctity of these months. Then Saeed was asked: If someone injures another in these months, will you also increase the blood money for that, just as you increase it for murder? Saeed replied: Yes.
Imam Malik, may Allah have mercy on him, said: I think that what is meant by the increase by those two persons is the same as what Sayyiduna Umar, may Allah be pleased with him, did in the blood money of the Mudliji, when he killed his son.
