Qais said:
Abu Bakr stood up and praised and glorified Allah, then he said: O people, you recite this verse: “O you who believe! Take care of your ownselves. If you follow the (right) guidance...” [al-Ma'idah 5:105], but you do not interpret it properly. I heard the Messenger of Allah (ﷺ) say: “If the people see evil and do not change it, soon Allah will send His punishment upon them all.` He (Qais] said: I heard Abu Bakr say: O people, beware of lying for lying is contrary to faith.
