I came across the verse that mentions polygamy in the Quran the other day and I noticed something, the verse says:
"And if ye fear that ye will not deal fairly by the orphans, then marry of the women, who seem good to you, two or three or four; and if ye fear that ye cannot do justice (to so many) then one (only) or that your right hands possess. Thus it is more likely that ye will not do injustice." [4:3]
It shows in the verse that there's a special case where polygamy is allowed..
"And IF ye fear that ye will not deal fairly by the orphans, THEN marry of the women, who seem good to you, two or three or four".. There's also a condition that should be met and that is to treat all wives justly..
Could it be that polygamy is only allowed for the sake of taking care of widows and orphans?
Also, how to reconcile between the above mentioned verse and
Ye will not be able to deal equally between (your) wives, however much ye wish (to do so). But turn not altogether away (from one), leaving her as in suspense. If ye do good and keep from evil, lo! Allah is ever Forgiving, Merciful. [3:129]
