Multiple Marriages?

4:1

يَـٰٓأَيُّہَا ٱلنَّاسُ

O mankind

ٱتَّقُواْ رَبَّكُمُ

Fear your Lord

ٱلَّذِى خَلَقَكُم مِّن نَّفۡسٍ۬ وَٲحِدَةٍ۬T

The one who created you from a single soul

وَخَلَقَ مِنۡہَا زَوۡجَهَا

and created from it,its mate

وَبَثَّ مِنۡہُمَا رِجَالاً۬ كَثِيرً۬ا وَنِسَآءً۬‌ۚ

and dispersed from them,many men and women

‌ۚ وَٱتَّقُواْ ٱللَّهَ ٱلَّذِى تَسَآءَلُونَ بِهِۦ

and fear Allah whom you ask with it

وَٱلۡأَرۡحَامَ‌ۚ

and the wombs (relations)

إِنَّ ٱللَّهَ كَانَ عَلَيۡكُمۡ رَقِيبً۬ا (١)

Allah is over you Ever-Watchful.(1)

............

4:2

وَءَاتُواْ ٱلۡيَتَـٰمَىٰٓ أَمۡوَٲلَہُمۡ‌ۖ

and give ORPHANS (helpless children, women, widows..etc)their wealth

وَلَا تَتَبَدَّلُواْ ٱلۡخَبِيثَ بِٱلطَّيِّبِ‌ۖ

and do not exchange the bad with the good

(means do not exchange your bad things with their good things)

وَلَا تَأۡكُلُوٓاْ أَمۡوَٲلَهُمۡ إِلَىٰٓ أَمۡوَٲلِكُمۡ‌ۚ

and do not consume their wealth with your wealth

(do not mix-up their wealth with yours to eat-up!)

إِنَّهُ ۥ كَانَ حُوبً۬ا كَبِيرً۬ا (٢)

indeed it is a sin. (2)

4:3

وَإِنۡ خِفۡتُمۡ أَلَّا تُقۡسِطُواْ فِى ٱلۡيَتَـٰمَىٰ

if you fear that you can't deal fairly with orphans (under-discussion)

فَٱنكِحُواْ مَا طَابَ لَكُم مِّنَ ٱلنِّسَآءِ

Then marry them what is suitable or easy for you, amongst the women

(obviously "orphan" women eligible to be married)

مَثۡنَىٰ وَثُلَـٰثَ وَرُبَـٰعَ‌ۖ

two, and(or) three and(or) four

فَإِنۡ خِفۡتُمۡ أَلَّا تَعۡدِلُواْ فَوَٲحِدَةً

but if you fear,that you cant do justice, then ONE

أَوۡ مَا مَلَكَتۡ أَيۡمَـٰنُكُمۡ‌ۚ ذَٲلِكَ أَدۡنَىٰٓ أَلَّا تَعُولُواْ (٣)

or what your right hand possesses (3)

(means already under your guardianship)

Another Aspect:

فَٱنكِحُواْ So Marry them to someone eligible...

May NOT mean always, that you marry with them, but, it can be MARRY THEM with someone suitable , or find a match for them to marry them.

Anyways the subject may deal with the Multiple Marriages ...which were recommended after the Battle of Uhad ,when many Muslim men lost their lives ...leaving their wives and children ,helpless...

The subject become clear with these words...

4:19,20,21

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا يَحِلُّ لَكُمۡ أَن تَرِثُواْ ٱلنِّسَآءَ كَرۡهً۬ا‌ۖ وَلَا تَعۡضُلُوهُنَّ لِتَذۡهَبُواْ بِبَعۡضِ مَآ ءَاتَيۡتُمُوهُنَّ إِلَّآ أَن يَأۡتِينَ بِفَـٰحِشَةٍ۬ مُّبَيِّنَةٍ۬‌ۚ وَعَاشِرُوهُنَّ بِٱلۡمَعۡرُوفِ‌ۚ فَإِن كَرِهۡتُمُوهُنَّ فَعَسَىٰٓ أَن تَكۡرَهُواْ شَيۡـًٔ۬ا وَيَجۡعَلَ ٱللَّهُ فِيهِ خَيۡرً۬ا ڪَثِيرً۬ا (١٩) وَإِنۡ أَرَدتُّمُ ٱسۡتِبۡدَالَ زَوۡجٍ۬ مَّڪَانَ زَوۡجٍ۬ وَءَاتَيۡتُمۡ إِحۡدَٮٰهُنَّ قِنطَارً۬ا فَلَا تَأۡخُذُواْ مِنۡهُ شَيۡـًٔا‌ۚ أَتَأۡخُذُونَهُ ۥ بُهۡتَـٰنً۬ا وَإِثۡمً۬ا مُّبِينً۬ا

وَكَيۡفَ تَأۡخُذُونَهُ ۥ وَقَدۡ أَفۡضَىٰ بَعۡضُڪُمۡ إِلَىٰ بَعۡضٍ۬ وَأَخَذۡنَ مِنڪُم مِّيثَـٰقًا غَلِيظً۬ا (٢١)

4:19 O ye who believe! Ye are forbidden to inherit women against their will. Nor should ye treat them with harshness, that ye may Take away part of the dowery  have given them,-except where they have been guilty of open lewdness; on the contrary live with them on a footing of kindness and equity. If ye take a dislike to them it may be that ye dislike a thing, and God brings about through it a great deal of good.

4:20 But if ye decide to take a wife in place of another, even if ye had given the latter a whole treasure for dower, Take not the least bit of it back: Would ye take it by slander and manifest wrong?

4:21 And marry not women whom your fathers married,- except what is past: It was shameful and odious,- an abominable custom indeed.

And how could ye take it when ye have gone in unto each other, and they have Taken from you a solemn covenant?

This subject becomes more clear ,Inshallah!...when we study the following verses of the same Surah ,carefully, which are connected to the main subject of ORPHANS...

4:127     And they ask you a decision about women. Say: Allah makes known to you His decision concerning them, and that which is recited to you in the Book concerning female orphans whom you do not give what is appointed for them while you desire to marry them, and concerning the weak among children, and that you should deal towards orphans with equity; and whatever good you do, Allah surely knows it.

4:128     And if a woman fears ill usage or desertion on the part of her husband, there is no blame on them, if they effect a reconciliation between them, and reconciliation is better, and avarice has been made to be present in the (people's) minds; and if you do good (to others) and guard (against evil), then surely Allah is aware of what you do.

4:129     And you have it not in your power to do justice between wives, even though you may wish (it), but be not disinclined (from one) with total disinclination, so that you leave her as it were in suspense; and if you effect a reconciliation and guard (against evil), then surely Allah is Forgiving, Merciful.

4:130     And if they separate, Allah will render them both free from want out of His ampleness, and Allah is Ample-giving, Wise.
