Is this hadith authentic?

There is a hadith about Umm Hani approaching the Prophet (ﷺ), and she asked him for a good deed that she could do because she had become old and weak. The Prophet (ﷺ) said that if she said Subhanallah 100x, it would be equivalent to freeing 100 slaves from the children of Ismail, and if she said Alhamdullilah 100x, it would be equivalent to sending 100 horses to battle in the way of Allah for jihad, and if she said Allahuakbar 100x, it would be as if you dressed 100 camels to get sacraficed in Hajj. I can't find much information about the validity of this hadith online, so does anybody know if it is authentic or not?
