Why Tzedakah's Rabbi Meir Baal Haness ?
There is a Minhag (custom) to give Tzedakah (Charity) to the Tzedakah of Rabbi Meyer Baal Haness when one is in a situation of any need or distress. This custom has its roots in the Talmud. Prior to Rabbi Meyer Baal Haness's passing he observed the terrible situation that resulted from the hunger in Eretz Yisrael. He proclaimed that he would intercede for whoever would give Tzedakah for his Neshamah, and the money should be distributed to the poor of Eretz Yisrael.
When one donates Tzedakah to this fund should first give the money
and then say, "G-d of Meir answer me."
Some have the custom when they lose something to immediately promise to give some money to the Tzedakah of Rabbi Meyer Baal Haness in the merit of finding what was lost, and say the following.
One must also make sure that the money goes to a help the poor in Eretz Yisrael because that is what Rabbi Meyer Baal Haness intended.
