Is it permissible to send the price of admission tickets by mail, and is it necessary to go to the UAE to deliver the amount, or is it sufficient to clarify what happened?

To free oneself from an obligation, it is required to deliver the right to the deserving party, even through indirect means, without informing them. Thus, sending the amount by mail, depositing it into an account, or sending it to someone who will deliver it to the responsible party is sufficient, based on the hadith (definition): "On the hand is what it has taken until it fulfills it," and the saying of the Prophet, peace and blessings be upon him: "Whoever has wronged his brother concerning his honor or anything else, let him seek his forgiveness today before there will be no dinar or dirham."
