Is a funeral prayer performed for a deceased Muslim in Europe and in his home country, and is he buried in his home country based on his will, and what are the best recommendations that can be made to family and friends?

Transporting the deceased and burying them in a country far from their place of death is permissible if there is a benefit in doing so, especially if the deceased willed it. The funeral prayer can be performed either at the place of death or the place of burial, and it is preferable not to repeat the prayer. As for a lawful will, the best kind is that in which all obligatory rights are fulfilled, such as the debts of the deceased, their duties towards Allah, and their rights over people, in addition to enjoining their family to piety and caring for the poor and needy.
