Is it obligatory to believe the neighbor and pay the amount she claims to have given to the deceased, especially since the deceased did not trust her words and denied receiving the money, and there is no proof of the neighbor's claim?

The reference for disputes and litigations in this chapter is based on the rule: "The burden of proof is on the claimant, and the oath is on the one who denies." So, the claimant woman must prove her claim, and if she cannot, then those who deny must swear an oath that they do not know about it, and mention their grandmother's denial. This is what is legally required if the grandmother left an inheritance. However, if it is highly probable that the woman is truthful and the grandmother is untruthful, it is recommended to give her her right from the grandmother's inheritance. And if she has no inheritance, then donating to her is a good deed.
