God forbade adoption (see
33:4,
33:5), so that Mohamed could marry her daughter in law (see
33:37,
Zainab)
Allah has not made for a man two hearts in his interior. And He has not made your wives whom you declare unlawful your mothers. And he has not made your adopted sons your [true] sons. That is [merely] your saying by your mouths, but Allah says the truth, and He guides to the [right] way. - Quran Al-Ahzab(The Confederates) 33:4 (islam)
Call them by [the names of] their fathers; it is more just in the sight of Allah. But if you do not know their fathers - then they are [still] your brothers in religion and those entrusted to you. And there is no blame upon you for that in which you have erred but [only for] what your hearts intended. And ever is Allah Forgiving and Merciful. - Quran Al-Ahzab(The Confederates) 33:5 (islam)
And [remember, O Muhammad], when you said to the one on whom Allah bestowed favor and you bestowed favor, "Keep your wife and fear Allah," while you concealed within yourself that which Allah is to disclose. And you feared the people, while Allah has more right that you fear Him. So when Zayd had no longer any need for her, We married her to you in order that there not be upon the believers any discomfort concerning the wives of their adopted sons when they no longer have need of them. And ever is the command of Allah accomplished. - Quran Al-Ahzab(The Confederates) 33:37 (islam)
Chapter: “…And His Throne was on the water…”
Narrated Anas:
Zaid bin Haritha came to the Prophet (ﷺ) complaining about his wife. The Prophet (ﷺ) kept on saying (to him), "Be afraid of Allah and keep your wife." Aisha said, "If Allah's Messenger (ﷺ) were to conceal anything (of the Qur'an he would have concealed this Verse." Zainab used to boast before the wives of the Prophet (ﷺ) and used to say, "You were given in marriage by your families, while I was married (to the Prophet) by Allah from over seven Heavens." And Thabit recited, "The Verse:-- 'But (O Muhammad) you did hide in your heart that which Allah was about to make manifest, you did fear the people,' (33.37) was revealed in connection with Zainab and Zaid bin Haritha." - Hadith Al Bukhari 7420 (islam)
