I have read Quran several times and Janab still I can tell you over and over again no permission from first wife is required. This law is not based on Quran and Sunnah but totally opposite to it.
Bai mayray you have read Quran several times but apparently you haven't understood the true spirit of Quran.
The non permissions and haram have been clearly told in Quran. Quran keeping silent in itself doesn't qualify as something haram. Now will you please quote a verse that clearly prohibits a state to formulate a law that needs the husband to seek permission from his first wife for second marriage?
You are transgressing really by saying that this law is not in accordance with Quran.
And it's not protecting women rights Janab only creating more issues in society the cases of wife either getting divorced and thrown out of house with no one to care off because she didn't allowed husband 2nd marriage or even worse getting killed are increasing massively.
For goodness sake ....... a just civilised law cannot be blamed for how animals behave. Please try understanding that and put the blame on party that deserves it ....... in this case men who wish to sleep with different women not because they feel those women are poor helpless and dependent but because they themselves have urge to have sex with different women.
Sorry this freedom is what ALLAH and his RASOOL SAW have given followed by Sahabas and let me remind you lot of Sahabas were seriously poor still many of them had more than one wife. You need to do ALLAH ka khauf and stop justifying a Haram thing.
Can you mention how long Hazrat Khadeeja (May ALLAH be pleased with her) remained in nikkah with Muhammad Peace be upon him and did Muhammad peace be upon him marry another woman in her presence? Can you please equate all marriages of Messenger Peace be upon him with marriages of any other person ....... the intent and purpose behind those marriages? Do you even know why Muhammad Peace be upon him married Ayesha (May ALLAH be pleased with her). And stop painting all of the companions of Messenger as poor and destitute ......
