Malik related to me that Ismail ibn Abi Hakim heard Umar ibn Abd
al-Aziz say, "Some say that Allah the Blessed, the Exalted, will not
punish the many for the wrong action of the few. However, when the
objectionable action is committed openly, then they all deserve to be
punished."
Muwatta Malik Book 56, Hadith 23
