Malik related to me from Ishaq ibn Abdullah ibn Abi Talha that Anas ibn Malik said, "I heard Umar ibn al-Khattab, when I was going out with him to visit an orchard, say to himself, and there was a wall between him and me and he was inside the garden, 'Umar ibn al-Khattab, amir al-muminin! Well done! Well done! By Allah, fear Allah or he will punish you.' "
Muwatta Malik Book 56, Hadith 24
← Previous Hadith 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 Next Hadith → Malik said, "I heard that al-Qasim ibn Muhammad used to say, 'I have seen the people, (i.e. the companions), and they were not impressed by speech.' " Malik said, "He meant that only action and deeds would be looked at, not words."
