Am I religiously obligated to pay the equivalent of 100 grams of gold at today's price, or the equivalent of 3,000 Egyptian pounds at the time the list was written, knowing that I did not agree upon the number of grams, and it may have been added later?

It is obligatory for the man to give his wife, upon divorce, the deferred dower and the first installment of the immediate dower as agreed upon. If the agreement was to pay three thousand pounds and this was written in the dower list, then this amount must be paid regardless of the value of the gold. However, if the agreement was to pay a specific quantity of gold, then that quantity must be paid.
