All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
First of all, praise be to Allah, who conferred His favors upon you and enabled you to embrace Islam and guided you to His true Religion and His straight Path. This is indeed the greatest blessing and favor.
We ask Allah to make you firm on this true religion and enable you to be grateful for this blessing.
You should know that your husband's keenness that you hasten to start wearing the hijaab is the correct attitude that is in compliance with the Shariah (Islamic Law), and it reflects the required jealousy of a man over his wife and his responsibility of being her guardian and protector.
Therefore, you are obliged to hasten to wear the hijaab and not procrastinate on the grounds of preparing your family for this matter. Your obedience to your Lord and compliance with the Shariah comes in priority over everything else. Life is short ,and death comes suddenly. For more benefit, please refer to fatwa 83765.
As regards visiting your family, this is permissible provided that this does not spoil your religion and does not constitute a participation in their non-Muslim festivals.
For more benefit, please refer to fatwas 126163 and 140790.
Allah knows best.
