One day, the Messenger of Allah (may Allah's peace and blessings be upon him) gave us an eloquent admonition that caused hearts to become afraid and eyes to shed tears. Someone then said: O Messenger of Allah, this is the admonition of someone who will soon part; so, advise us. He said: "I advise you to fear Allah and to hear and obey, even if an Abyssinian slave. You will see after me great discord. So, hold fast to my Sunnah and the Sunnah of the rightly guided Caliphs. Bite onto it with the molar teeth. Beware of newly invented matters (in religion), for every newly invented matter is misguidance."

"When people see an oppressor but do not stop him, Allah will soon overwhelm them with a punishment from Him."

"Among the best of Jihad is to speak a word of justice to an oppressive ruler."

"I advise you to fear Allah, and to listen and obey even if a slave is appointed as your leader. Whosoever among you shall live after me will see much discord. So hold fast to my Sunnah and the Sunnah of the Rightly-Guided Caliphs, and cling to them firmly. Beware of new things (in religion) because every religious innovation is a misguidance."

"Let not the fear of people prevent any man among you from speaking the truth when he sees it or knows it."

The Messenger of Allah (may Allah's peace and blessings be upon him) delivered a speech on the day of the Conquest of Makkah. He said: "O people, verily Allah has removed the arrogance of jāhiliyyah from you and their boastfulness about their forefathers. So, now, there are two types of men: a righteous, pious, and honorable person in the sight of Allah and a wicked, wretched, and insignificant person in the sight of Allah. People are the children of Adam, and Allah created Adam from dust. Allah says: {O mankind, We have created you from a male and a female, and made you into nations and tribes so that you may recognize one another. Indeed, the most noble of you before Allah is the most righteous among you. Indeed, Allah is All-Knowing and all-aware.} [Surat al-Hujurāt: 13]"
