All but two ; Safiya who was a Jew , and Mariya who was a Christian .
Now, let’s answer the main and very important question: Was it lust that caused the prophet (PBUH) to have so many marriages?
<ul><li>To answer the question we have to mention the following facts: </li></ul>
1- The Prophet married for the first time when he was 25 years old.
2- The first woman he married , Khadijah was 40 years old already married twice before him and had children. He stayed married to her alone for 25 years , until she died. He stayed single after her death for two years in grief and mourning over her death . He was then 52 years old.
3- From 52 till 60, he married several times for political and social reasons, not for lust (Naooz Billah)…. After two years of living single , he married Sawdah, an 80 year old widow in order to honor her because she was the first widow in Islam. Not an act of a lustful man after a period of living single.
It’s not logical to say that lust had appeared suddenly at the Prophet’s life at 52, and at the middle of the fierce physical and psychological struggle to spread Islam
There is only one conclusion we can extract from the above: 1- Mohammad (PBUH) the man married Khadijah 2- Mohammad (PBUH) the Prophet married the rest of his wives.
But , was Mohammad (PBUH) the only Prophet to have multiple wives? Or polygamy was taken by other Prophets as well?
The answer is : NO. Polygamy was the norm at the times of Ibrahim, Dawoud, Solayman, all known in the Bible to have been polygamists.
Now, let’s mention the political, social and religious reasons the prophet (PBUH) had these marriages.
First: To spread the culture through eyewitnesses with all the details known only to intimate people. Hazrat Aaishah (R.A), being so young, was able to tell all those details to the Muslims for more than 42 years. She had seen and learnt so much from him. Her young age was a great advantage in this respect. She could tell what the Prophet (pbuh) used to do or say in all aspects of life, so that people do and say the same in the similar situations…
Hazrat Aaishah (R.A), was the most knowledgeable person when it comes to the daily life of the Muslims and how it should go as was lived by the Prophet (PBUH) himself . But how can he (PBUH) married her when she was only nine years old? The desert climate answers to that . In such environment Girls reached youth very young. Not only in Arabia, but also in Roma and Persia, girls were married that young
Second: To strengthen the relationships with his companions, he married Abi Bakr’s daughter and Omar's sister, married his daughters to Othman and Ali, May God be pleased with them all.
Third: out of mercy and rewarding the early Muslim widows and divorcees he (PBUH) gave them the honor of marrying them himself (Husbands either died in battles or were non Muslims who divorced them.). Sawdah, Om-salama and Habeebah were widows.
Fourth: The Prophet (PBUH) was being a role model for the Muslims being kind to the widows and to the people of the book who newly embraced Islam. He (PBUH) married Safiyah after her father , a Jew, embraced Islam , so giving him and his daughter the honor among his people
Fifth: He (PBUH) wanted to have ties and links with the different nations of the world. When he married Mariya, all Egyptians were on his side, and when he married Gowayriyah, all her people (they were called the Bani Almustalaq and were captured by the Muslims after a battle),, they all embraced Islam
I wish this makes you more assured and able take a stand up to allegations against the Prophet (PBUH). May peace, mercy and blessings of Allah be upon you all.
