Q. If two people have yohrzait on the same Shabbos, can they cast a Goral Ha’grah or any other lots or raffle, to decide who gets maftir.
If the one who gets Maftir also pays for the kiddush after davening, can they still do it?
A. Horav Shlomo Miller’s Shlit’a opinion is that making a goral or casting lots could be done on Shabbos, when the lottery does not involve any monetary decisions.
In this case both parties should previously agree in concert with the Gabaim of the shul, that the expenses for the kiddush should be offered, when a Mi Sheberach is recited for the one who wins the raffle and receives the Maftir.
