Q. Re- question above if one sleeping can be counted for a minyan. If he does count as one of the first ten, and he feels that he is falling asleep, should he better stay inside the shul, and not go to another room for a fast nod off?
A. On question 2152 regarding sleeping in a shul or beis medrash we wrote: “Shulchan Aruch (O.H. 151: 2-3) permits sleeping in a beis hameresh and in need even in a shul, Mishna Berura (ibid. 16) quoting R’A Eiger debates the permissiveness, but concludes that for a Talmid Chacham who constantly learns there, even a night sleep is acceptable.
Kinyan Torah (4: 15) quoting Divrei Chaim mentions that there is added leniency in Chassidik shuls that were established with specific tolerant conditions and therefore referred to as a “shtivel” or a room.
However, Horav Shlomo Miller’s Shlit’a opinion is that it is better, for the kavod and honor of the beis hamedresh to exit to another room and sleep there even temporarily, when possible.”
The Rov maintains that the same would apply in this case, once there is a minyan without him.
