Dr. Monzer Kahf, a prominent economist and counselor states: “To spend on Umrah from the use of credit cards or from financing facilities from Islamic banks with the condition of paying the credit card within the grace period and the financing facilities on time, that is permissible and the Umrah fulfills its conditions from this financial angle. Every muslim also needs to remember that a person who has no funds readily available for Umrah/Hajj is not required to go for it as either of them is then not obligated on this person.”
Allah Almighty knows best.
