It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him), he says: On the day of the conquest of Makkah, I was standing beneath the mount of the Messenger of Allah (peace and blessings be upon him). The Prophet (peace and blessings be upon him) spoke very beautiful and eloquent words. Among them was this:“Whoever from among the People of the Book becomes a Muslim, he will have a double reward, and then whatever right is ours will also be his, and whatever responsibility is upon us will also be upon him. And whoever from among the polytheists becomes a Muslim, he will receive his reward, and then whatever right is ours will also be his, and whatever responsibility is upon us will also be upon him.”
