what is the probability of it happening? does it prove the God of Judaism?

i will summarize it and propose an estimation

>rabbi has a bill every once a month, he was still living in NY
>rabbi's wife informs rabbi they need exactly 6,000 dollars by the next day (last day to pay the bill)
>there's zero dollars in the bank
>rabbi says that's God's problem, starts a conversation
>says "He brought us this far for what? to destroy us?"
>immediately after this sentence
>rabbis gets an unidentified phone call
>it's someone he lended 5,000 dollars 8 years ago and disappeared, says he's sorry and wants to pay him back
>rabbi gives bank account
>an hour later, rabbi gets a deposit of exactly 6,000 dollars
>rabbi calls asking if the guy made a mistake (jews cant take interest on other jews)
>guy says it's 5,000 he owned plus 1,000 present for the lectures

at best the chance is 1/2921 just choosing random days in 8 years (not counting lending day), but when you add the restriction of one day before the bill (only 1 out every 30 meet the constraint), the chance is 1/87630. you also need to multiply this by the chance of the guy donating 1,000 dollars on top of the change of giving the full 5,000, for simplification purposes i would say the chance of giving 5,000 (instead of 2,000 that day and 3,000 new week for example) is 1/5 and the chance of giving 1,000 on top is 1/2 (due to traditional tzedakah being only at most 20% of your earnings, assuming only 5,000 were eaned that period).

Final simplified estimation is 1/876300. The chance should be even lower but i don't know the rate the rabbi picks up the phone if the calls are unidentified.
