Did Prophet Muhammad (Peace Be Upon Him) really marry A'isha at the age of 9 years old and Prophet Issac (Peace Be Upon Him) really marry Rebecca at the age of 3 years old?

Abstract This paper discusses the fictitious marriages of both Prophet Muhammad (Peace Be Upon Him) with A’isha at the age of 9 years old and Prophet Issac (Peace Be Upon Him) with Rebecca at the age of 3 years old. According to a good number of Jewish, Christian, and Hindu opponents of Islam, Prophet Muhammad (Peace Be Upon Him) was a sexual pervert and pedophile because he was betrothed to A’isha at the age of 6 years old and married her at the age of 9 years old following consummation of the marriage. On the other hand, according to a good number of Muslim and Hindu opponents of Judaism, Prophet Issac (Peace Be Upon Him) was a sexual pervert and pedophile because he married Rebecca at the age of 3 years old. Which is which as far as the marriages of both Prophets (Peace Be Upon Them) are concerned? Were they really both sexual perverts and pedophiles who really married young girls and children below 10 years old?
