ISLAMIC PROPHET LUSTS FOR HIS OWN ADOPTED SON'S WIFE, ZAYNAB

Muhammad visited his adopted son at his residence.

And Islamic Prophet Muhammad keeps repeating "Glory be to God the Almighty! Glory be to God, who causes hearts to turn!”

So, Allah protected Muhammad by revelation in Quran 33:37;

“And, 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."

Knowing that Muhammad was interested in his (Zayd) wife and endorsed by Allah, he decided to divorce his wife for the sake of Muhammad.
