Is it permissible for a woman to give charity on behalf of a deceased man who is not a relative, whether by money, prayer, fasting, or reciting the Qur'an?

The questioner : Is it permissible for a woman to give charity on behalf of a deceased man who is not a relative, whether by money, prayer, fasting, or reciting the Qur'an?

The Shaykh : The correct view is that this is permissible, and that any Muslim who volunteers to perform a prayer, give charity, fast, perform Hajj, or perform 'Umrah on behalf of another Muslim is acting permissibly. However, we do not advise this, and we say that whoever wants to benefit his brother should make du'a for him, based on the saying of the Prophet (peace and blessings be upon him) He said, and he did not say, "or a righteous son who gives charity on his behalf, or prays on his behalf, or the like." Yes.
