Ali baba celebrates wife on her 50th birthday
I think there may be a bit of a problem here!
Ali Baba is a character from a classic Middle Eastern folk tale, "Ali Baba and the Forty Thieves". He is a poor woodcutter who discovers a magic cave filled with treasure, and uses the magic phrase "Open Sesame" to gain access to it.
As Ali Baba is a fictional character, he doesn't actually exist, so he can't celebrate his wife's 50th birthday or any other occasion. Additionally, the story of Ali Baba and the Forty Thieves doesn't mention Ali Baba having a wife or celebrating any birthdays.
If you'd like, I can help you come up with a fictional scenario or story about Ali Baba celebrating his wife's 50th birthday, but it would be purely imaginative and not based on any actual events or characters from the original tale.
