Encyclopedia of Prophetic Hadiths

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."

We were on a journey with the Messenger of Allah (may Allah's peace and blessings be upon him) when he went to relieve himself. We then saw a Hummarah (a type of bird) with its two chicks. We took its chicks, and the bird came back and began to flap its wings. Upon seeing it, the Prophet (may Allah's peace and blessings be upon him) came and said: "Who has distressed it by taking its baby? Return its baby." He then saw an ant colony that we had burned, and he said: "Who burned this?" We said: We did. He said: "No one should punish with fire except the Lord of fire."
