Dr. Monzer Kahf, a prominent economist and counselor states: It is definitely permissible of course to go for Hajj with a loan, as long as the loan is without interest and the one taking the loan has the ability and the plan to repay it back in due time. Interest-based loans because they are Haram have priority over Hajj but not any debt is like that. Debts that are not due and for them one has a payment plan and ability don’t have priority over Hajj.”
