Is a father's gift of money to his son valid if the father was intoxicated at the time of the gift, but then affirmed the gift after sobering up?

Scholars differed regarding the ruling on a gift from an intoxicated person. One school of thought held that their buying, selling, and all their contracts, whether beneficial or harmful to them, are valid. Others maintained that none of their actions are valid. A third group distinguished, stating that their actions regarding what is due to them are valid, but not those concerning their property. According to this view, their selling and gifting are valid, but not their pledging. The preponderant view is that the gift of an intoxicated person who is voluntarily intoxicated is not valid. However, if the father knows of your consent to the money, there is no harm for you in benefiting from it. It is obligatory to forbid the father if he becomes intoxicated by something prohibited, such as drinking alcohol.
