Musannaf Ibn Abi Shaybah

Hazrat Saeed bin Musayyib, Hazrat Sulaiman bin Yasar, and Hazrat Ata said: When someone is killed within the boundaries of the Haram, there will be blood money (diyat) and one-third of the blood money. And if someone is killed during the sacred months while in the state of Ihram, then an aggravated blood money (diyat mughallazah) will be obligatory, meaning a stricter form of blood compensation.
