Question : Can I go on Hajj if my wife is financing it?
Answer : If your wife is willingly financing the trip, then:(1) It would fulfill your obligation to perform Hajj–as having the means to pay for the trip is a condition for Hajj being obligatory upon one, not a condition of validity; and
(2) Your wife would have the reward of both her Hajj and of facilitating your Hajj.
[ref: Ibn Abidin, Radd al-Muhtar]
And Allah alone gives success.
