Rabbi Meir Ba'al ha Ness - Master of the Miracle

Yarzheit: 14 Iyar

Ohel of Rabbi Meir Ba'al HaNess

By simply saying the phrase אלהא דמאיר ענני "Eloka d'Meir aneini" three times , which means "the G-d of Meir Answer me !", a person will be saved from trouble, if they promise to give charity to the poor and needy in the memory of the soul of Rebbe Meir Baal Haness .

The Chida says that the source for this custom is the Gemara [Avodah Zara 18a-b] where Rebbi Meir bribed a guard to release his imprisoned sister-in-law.

Mesechta Sanhedrin 100b explains this as ישיחנה לאחרים, tell it over to others. Mesechta Horios 13b says אחרים refers to Rebbi Meir. Putting it all together – if one is in a time of trouble give tzedaka for the neshama of Rebbi Meir Baal HaNess.  [Source: Tzemach Dovid]
