Is it permissible for a traveler to give Sadaqa in the town he has stopped in, even if only for a few days?

It is permissible to give charity in the country a person has traveled to, even if only for a few days, because charity is an act of worship and obedience that is not restricted to a specific country. However, it is preferable to give charity to the poor in countries with greater need, and to disburse it to needy relatives.
