Q. In these covid 19 days, when we are asked to daven at home, is there a hiddur (enhancement) for several people (sons and father) davening at the same time and same place, even though there is no minyan?
A. Our Sages teach that; One cannot compare the many performing a mitzva (or learning Torah), to the few doing it. (Sifra Bechukosai 2: 3, Rashi 26: 8, et al). A reflection to the verse: “Berov Am – In multitudes there is glorification of the King” (Mishle 14:28). Poskim debate whether this applies even to only two individual also (See Shulchan Aruch O.H. 8: 5 – 298: 14 and Mishna Berura ibid. 13).
Therefore, Horav Shlomo Miller’s Shlit’a opinion is that if these are family members or people as is currently staying in the house, when keeping the necessary precautions, it is better if they daven at the same time and in the same place.
