Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
Dear sister, thank you for your question and for your commitment to Islam’s rulings concerning the Islamic dress code.
We are so sorry to hear that your husband rejects your hijab. A good Muslim husband should be more than happy that his wife has commitment to Allah’s orders.
Anyway, this is Allah’s order that you are obliged to follow whether it satisfies your husband, or any other human, or not.
In his response to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states,
You are not obliged to obey your husband on this matter. The Prophet (peace and blessings be upon him) said, “There is no obedience in matters involving disobedience to Allah. Obedience is only in the good deeds.” (Abu Dawud)
Since it is the order of Allah for women to wear hijab and cover their bosoms. You ought to observe this rule as best as you can. You should explain this to your husband. If he is a Muslim, he should be more than happy to encourage you in following Allah’s order.
You should kindly approach him trying to convince him that you do not want to expose yourself to the torture in the Hereafter. You can seek help from an influential friend or family member, or even a local imam.
Allah Almighty knows best.
