Reply To: Aruch Hashulchan

My father asked Rav Shlomo Zalman why the oilam uses Mishna berura over aruch hashulchan and he answered because the chafetz chaim put more ameilus into making the mishna berura (like chazering everything 35 times) But my father is unclear if he meant therefore the psak of the MB is more authoritative or min hashamayim it was more niskabel by the velt because of the yegiah.
