Is it permissible to use the travel allowance disbursed by a government entity for Hajj, knowing that the original trip to Ethiopia was hindered, and the alternative trip to Saudi Arabia for administrative clearance has no specific mission and coincides with the days of Hajj?

The employee must return the money disbursed to him for a task that was not performed, for the Prophet, peace and blessings be upon him, said: "Muslims are bound by their conditions." If the condition for the entitlement of travel allowance is not met, then its entitlement is void. If your superior directs you to travel to another country, it is not permissible to take the money if it is a trick to take it unlawfully. However, if the superior is authorized to do so and it is not a trick, there is no objection to taking the money. If your travel coincides with Hajj, there is no objection to performing Hajj as long as it does not prevent you from your obligatory work for which you received the money, because your benefits at this time belong to the entity that sent you.
