How sound is the Hadith: "There is no woman who gives her dowry in charity to her husband before he consummates the marriage with her, but Allah will write for her for every Dinar the freeing of a slave," and the Hadith that follows it?

The aforementioned hadith (definition) with this specific wording has not been found in the available sources. However, in Al-Daylami's Musnad al-Firdaws, there is a hadith that states: "There is no woman who gives her husband anything from her dowry in charity before he consummates the marriage with her, but Allah will write for her two rak'ahs of a high rank for every dinar." The authenticity or inauthenticity of this hadith has not been verified.
