My mother is 95 years old. Can I perform Hajj-e-e-Badal for her?

Answer

If your mother is genuinely unable to undertake the journey and perform her Fardh Hajj, then it will be permissible for you to perform it on her behalf with her instructions and her money, not with your money. If you will be paying and if the Hajj is Fardh on your mother, then the Hajj-e-Badal will not be valid. It will be a Hajj for yourself. However, you may still ask Allah Ta'ala to transfer the thawaab (reward) of the Hajj to your mother.

If you perform Hajj on her behalf after her death, but without her having left instructions, then you can only make dua and hope that Allah Ta'ala will accept the Hajj on behalf of your mother.
