Both husband and wife work, and the wife owns jewellery. Does the responsibility to pay Zakat fall on the husband (who is earning) or should the wife pay for her own Zakat?
ANSWER SIMPLIFIED EVEN FURTHER:
This has nothing to do with paying zakaat.
This is where zakaat does come in!
No, but he can pay for it if he wishes to do so, AND as long as the wife gives him permission to pay for it. If he doesn't want to pay for it, he does not have to, if the wife gives him permission to pay for it, he still doesn't have to pay for it.
Again, this has nothing to do with zakaat. Zakaat is not based on who is earning and how much is being earnt. It is based on what you have and how much you have had in your possession as accumulated wealth for a complete lunar year.
Yes she should, unless her husband offers to pay on her behalf and she gives him permission to pay. If she does not give him permission, he cannot pay for it. Likewise, if she gives him permission and he does not want to (or can't) pay for it, he does not have to. So the responsibility belongs to the wife.
The below fatwa could not be more suited to your question.
ORIGINAL SIMPLIFIED ANSWER:
Everyone pays their own zakat, however, someone can pay on your behalf if they want to for some extra reward from Allah, but no sin on them if they don't, as it's 100% their choice (voluntary) to pay for someone else. Also, zakat is not about who works, it's about the wealth you have had for a complete lunar year after necessary expenses.
Have a look at this fatwa: Source
I am Not an Alim, but Zakat is Fard in Islam, Like Salah( namaz), Roza(Fasting) etc it should only be given on which it is Fard (i.e women) why in this case only it is given by whom it is not fard??? Gold is not source of happiness od stability but a major pain in many household and should be abolished an alternative Jewellery should be use.
