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 peace time is a FRANK violation of the Qur'an).
