Sayyiduna al-Harith bin Malik (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say on the day of the Conquest of Makkah: "After this day, it will never be attacked again." Sufyan (may Allah have mercy on him) said: Its explanation is: "It will not be fought over disbelief."
Al-Harith bin Hisham al-Makhzumi (may Allah be pleased with him) — who was martyred on the Day of Yarmuk in the year 15 AH. He is al-Harith bin Hisham bin al-Mughirah bin Abdullah bin Umar bin Makhzum; his kunyah was Abu Abd al-Rahman, and his mother was Asma' bint Makhramah bin Jandal bin Amir bin Nahshal bin Darim bin Malik bin Hanzalah bin Malik bin Zayd Manat bin Tamim. He accepted Islam on the day of the Conquest of Makkah, was one of those whose hearts were to be reconciled (al-mu'allafah qulubuhum), and died in Syria in the year 18 AH.
