Al Qur'an
English Translation of Al-Qur'an
[5]. Surah Al-Ma'idah [The Table Spread With Food]
Ayat 33. The recompense of those who wage war against Allah and His Messenger and do mischief in the land is only that they shall be killed or crucified or their hands and their feet be cut off on the opposite sides, or be exiled from the land. That is their disgrace in this world, and a great torment is theirs in the Hereafter.
Hadith
English Translation of Hadith
Hazrat Abu Said Al-Khudri (May Allah be pleased with him) reported: Messenger of Allah 
[S.A.W.W](P.B.U.H) said, "Whoever amongst you sees an evil, he must change it with his hand; if he is unable to do so, then with his tongue; and if he is unable to do so, then with his heart; and that is the weakest form of Faith".
[Muslim].
Lesson : as mentioned above in Surah Al-Ma'idah Ayat 33. "The recompense of those who wage war against Allah and His Messenger and do mischief in the land is only that they shall be killed or crucified or their hands and their feet be cut off on the opposite sides, or be exiled from the land". This Hadith contains a very important prescription to prevent the Muslim society from all things which are forbidden in Islam. So long as Muslims adhered to it and ceaselessly and fearlessly performed their obligation of enjoining the right and forbidding the wrong, their society was largely safe from many evils, mischief's and sins.
