Does the Qur'an allow this?
Not at all!
Very often in the Qur’an 'You' pertains to, and addresses, the Muslim society.
A fabricated hadith ascribed to Hazrat Ayesha tells us that if you fear that you could not do justice with the wealth of the widows and orphans, marry other women of your choice 2,3,4 (And let the widows and orphans die on the street).
Here is the Qur’anic Truth:
4:3 If you fear that the society shall not be able to do justice with orphans, (as may happen in times of war and political turbulence, the government shall announce a state of Emergency). In order to accommodate widows and orphans, men of sound finances and character shall be encouraged to marry these widows; two, three, and four (4:127). If you fear that you shall not be able to deal justly, then you must not take additional wives, and may continue with what you already have (4:129). This will prevent injustice and financial hardship. (Second marriage during peacetime is a FRANK violation of the Qur’an)
