After the passing of the elder Sadagurer, there was a bit of a controversy among the followers of R. Isaac, the firstborn who later moved to Boyan, and the followers of his brother R. Israel who remained in Sadagura.
Sadagurer Hasidim used to yell out in their synagogues [shtibelekh] during Simhat Torah the verse “Happy art thou, O Israel” [Deut. 33:29]. Conversely, the Boyaner Hasidim used to yell out during the Torah reading “[In] Isaac shall seed be called to thee” [Gen. 21:12].
