Did Prophet Muhammad peace be upon him really marry his daughter in law?
It is quite ironic that the haters of Islam try with their best attempts to discredit the True and Wonderful Religion of Allah Almighty, Islam, even if it were a lie and they knew that it was a lie.
One of the constant points that are usually brought up by the anti-Islamics against our beloved Prophet peace be upon him and Islam is the one where Muhammad married his adopted son's wife after they got divorced.
According to the Western culture, an adopted son becomes an actual son. But this law does not exist in Islam.
Let us look at Noble Verses 33:4-5 "Allah has not Made for any man two hearts in his (one) body: nor has He made your wives whom ye divorce by Zihar your mothers: nor has He Made your adopted sons your sons. Such is (only) your (manner of) speech by your mouths. But Allah Tells (you) the Truth, and He Shows the (right) Way."
Zihar is the divorce done by pagan Arabs before Islam, where a man would say to his wife you are to me like my mother. The man could marry another woman, where the woman couldn't marry another man, which was very degrading to all women.
Zayd's, the Prophet's alleged "adopted son" by the haters of Islam, wife, was the one who wanted to divorce him and marry the Prophet. She was not forced into the marriage by any means. Let us look at Noble Verse 58:1 "God has indeed heard (and accepted) the statement of the woman who pleads with thee concerning her husband and carries her complaint (in prayer) to God: and God (always) hears the arguments between both sides among you: for God hears and sees (all things)."
Let us look at Noble Verse 33:37 "Behold! thou didst say to one who had received the grace of Allah and thy favour: 'Retain thou (in wedlock) thy wife, and fear Allah.' But thou didst hide in thy heart that which Allah was about to make manifest: thou didst fear the people, but it is more fitting that thou shouldst fear Allah. Then Zayd had dissolved (his marriage) with her, with the necessary (formality), we joined her in marriage to thee: In order that (in future) there may be no difficulty to the believers in (the matter) of marriage with the wives of their adopted sons, when the latter have dissolved with the necessary (formality) (their marriage) with them. And Allah's command must be fulfilled."
According to Islamic laws, where from the above Noble Verses do we see our beloved Prophet Muhammad peace be upon him marrying his daughter in law?!
According to Noble Verses 33:4-5 above, we clearly see that an adopted son is NOT in the place of an actual son. An adopted son is a son from a stranger person. The foster father would still have to treat the adopted son with kindness and fulfill all of his needs. But the adopted son can never be an actual son.
According to Noble Verse 33:37 above, we clearly see that Allah Almighty allowed for the Muslims to marry the former wives of their adopted sons!.
If a man called another's son "his son", it might create complications with natural and normal relationships if taken too literally. The truth is the truth and can not be altered by men's adopting "sons". "Adoption" in the technical sense is not allowed in Muslim Law. Those who have been "wives of your sons proceeding from your loins" are within the Prohibited Degrees of marriage, but this does not apply to "adopted" sons; "Prohibited to you (for marriage) are your mothers, daughters, sisters; father's sisters, mother's sisters; brother's daughters, sister's daughters; foster-mothers (who gave you suck), foster-sisters; your wives' mothers; your step-daughters under your guardianship, born of your wives to whom ye have gone in no prohibition if ye have not gone in (those who have been) wives of your sons proceeding from your loins; and two sisters in wedlock at one and the same time, except for what is past for Allah is Oft-Forgiving, Most Merciful. (The Noble Quran, 4:23)"
Conclusion
Prophet Muhammad peace be upon him did not marry his daughter in law as the deceivers from the anti-Islamics always claim. Prophet Muhammad peace be upon him is a Great Messenger from Allah Almighty. Allah Almighty in the Noble Quran does not recognize an adopted son as a real son, because He, the Almighty, has His Great Wisdom behind it, to save us from complications and genetically and cultural problems.
