Answer
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.
In this fatwa:
You are allowed to use your credit card points for paying for Hajj or Umrah as they are yours and it is your right to use them in any halal way.
In his response to your question, Prof. Dr. Monzer Kahf, Professor of Islamic Finance and Economics at Qatar Faculty of Islamic Studies, states:
It should be clearly known that financing Hajj and Umrah must be from lawful halal income.
Yes, of course, it is permissible to use the rewards of your credit card for Hajj and Umrah. You own these reward points and you can use them for any purpose including going for Hajj or Umrah.
Having stated this, I hope that your credit card use was without any interest because interest is a grave sin as the Quran declares although the points are not accumulated on interest but on purchases, i.e., they are not affected by delay of payment.
Almighty Allah knows best.
