Is it acceptable to donate the price of two sacrificial animals as a vow for the benefit of those affected in Jenin via the Palestinian Embassy in Ankara, or must other needy people be found and the vow paid anew?

A vow must be fulfilled exactly as specified. It is not permissible to deviate from it except in cases of impossibility or for a greater benefit, such as giving money instead of food if that is more beneficial for the poor. If you vowed to slaughter two animals and distribute their meat to the poor without specifying a particular recipient, it is hoped that you have fulfilled your vow by donating their value to a trustworthy organization. If there is no strong presumption that the donation reached its intended recipients, then the vow must be fulfilled again for the deserving. If the vow was for a specific recipient, then it must be given to that specific party.
