Polygamy and a woman can’t marry more than one man at the same time:
( وَإِنْ خِفْتُمْ أَلَّا تُقْسِطُوا فِي الْيَتَامَى فَانْكِحُوا مَا طَابَ لَكُمْ مِنَ النِّسَاءِ مَثْنَى وَثُلَاثَ وَرُبَاعَ فَإِنْ خِفْتُمْ أَلَّا تَعْدِلُوا فَوَاحِدَةً أَوْ مَا مَلَكَتْ أَيْمَانُكُمْ ذَلِكَ أَدْنَى أَلَّا تَعُولُوا ) سورة النساء 3
And if you fear that you shall not be able to deal justly with the orphangirls,
then marry (other) women of your choice, two or three, or four
but if you fear that you shall not be able to deal justly (with them),
then only one or (the captives and the slaves) that your right hands possess.
That is nearer to prevent you from doing injustice. surah Al nsaa 3
Islam didn’t invent or ligislate polygamy.
Islam has come for all humans and to address all the diverse cultures.
The society which accepts polygamy and acknowledges it; and considers it one of the solutions to one of its problems.
Islam said polygamy is permissible with conditions.
For the cultures which can’t accept it, Islam didn’t impose polygamy.
Islam hasn’t ignored people’s problems or neglect them.
Rather, Islam has tackled them and suggested solutions for them, such as begetting children,
genealogy, emotions, and instinct, etc. Islam has found polygamy well established,
so Islam has dealt with it, refined it and put conditions and limitations for it.
This was to handle the matter without exaggeration or shortcomings,
otherwise it would deform the society and the loss of individuals.
( حُرِّمَتْ عَلَيْكُمْ أُمَّهَاتُكُمْ وَبَنَاتُكُمْ وَأَخَوَاتُكُمْ وَعَمَّاتُكُمْ وَخَالَاتُكُمْ وَبَنَاتُ الْأَخِ وَبَنَاتُ الْأُخْتِ وَأُمَّهَاتُكُمُ اللَّاتِي أَرْضَعْنَكُمْ وَأَخَوَاتُكُمْ مِنَ الرَّضَاعَةِ وَأُمَّهَاتُ نِسَائِكُمْ وَرَبَائِبُكُمُ اللَّاتِي فِي حُجُورِكُمْ مِنْ نِسَائِكُمُ اللَّاتِي دَخَلْتُمْ بِهِنَّ فَإِنْ لَمْ تَكُونُوا دَخَلْتُمْ بِهِنَّ فَلَا جُنَاحَ عَلَيْكُمْ وَحَلَائِلُ أَبْنَائِكُمُ الَّذِينَ مِنْ أَصْلَابِكُمْ وَأَنْ تَجْمَعُوا بَيْنَ الْأُخْتَيْنِ إِلَّا مَا قَدْ سَلَفَ إِنَّ اللَّهَ كَانَ غَفُورًا رَحِيمًا ) النساء 23
“ Forbidden to you (for marriage) are: your mothers, your daughters, your sisters,
your father’s sisters, your mother’s sisters, your brother’s daughters, your sister’s
daughters, your foster mother who gave you suck, your foster milk suckling sisters,
your wives’ mothers, your step daughters under your guardianship, born of your wives
to whom you have gone in – but there is no sin on you if you have not gone in them
(to marry their daughters), – the wives of your sons who (spring) from your own loins,
and two sisters in wedlock at the same time, except”“ for what has already passed;
verily, Allâh is OftForgiving, Most Merciful.” surah Al nsaa 23
Islam is the last heavenly message
Islam is the last heavenly message, before which there were many civilizations
with diverse cultures and norms. Some other than Muslims and till now believe in
and practise polygamy.
( polygamy ) Some non-Muslim polygamists have as many as ten wives,
such as the Mormons Christians. Such people think that what they do is right.
However, they suspect other cultures which are different from them.
Islam came to civilize this without fanaticism or dictatorship.
Islam has secured woman and ordered her not be the wife of more than one husband
at the same time.
However, this copes up with the sound instinct of women, so they aren’t married
to more than one husband.
This is to preserve genealogy and to ascribe a child to their father.
