Allah (swt) revealed:

“You are the best nation revealed for mankind. You enjoin what is right and forbid what is wrong and believe in Allah.” [TMQ 3:110]


The Messenger of Allah (saw) said:

“Whoever from amongst you sees an evil should change it by his hand, if he is unable to do so then he should change it by his tongue (by speaking against it), and if he is unable to do so then he should reject it in his heart and this is the weakest of Iman.” [Muslim]
Islam made it an obligation upon Muslims to enjoin the good and to forbid the evil no matter where they live and how big or small the good or evil may be. This is why we find Muslims across the world calling to the good or speaking against injustices regardless of whether they live in “democracies” or “dictatorships”. Individuals and organizations have been known to speak out against tyrant rulers in the Muslim world, for which reason their members have been tortured and in many cases murdered. Muslims are motivated by the words of Allah (swt) and His Messenger (saw) in their struggle against injustices.
Sheikh ibn Taymiyya mentioned three conditions for the issue of enjoining the good and forbidding the evil:

1.1. Knowledge prior to the action: This is in accordance to the issue, if the issue itself is well known to the Muslims such as abandoning the prayer, paying (riba) interest on a loan, or ruling by other than the Shari'ah then such matter does not require someone to be a scholar to enjoin or forbid.
2.2. Delivering the message in the most effective manner. This means we are firm, but avoid being harsh upon the person we are advising.
3.3. Patience after the action since whomever does this noble act will be afflicted with trials and tribulations by those they face. Allah (swt) revealed:
“By Al-'Asr (the time). Verily! Man is in loss, Except those who believe and do righteous good deeds, and recommend one another to the truth, And recommend one another to patience.” [TMQ 103Sometimes when Muslims engage themselves in debate with journalists and media outlets, the conversation ends with the Muslims being told that the only reason they are able to speak is because of the freedom of speech they are entitled to in democracies and that this is the reason they can be critical and disagree with others in the west.The fact of the matter is that even before the birth of the concept of free speech in Europe and America, Allah (swt) had revealed to the Muslims the concept of enjoining the good and forbidding the evil, as explained abovetype of mentality freedom of speech creates, a passive mentality to crime, towards other people's feelings and sentiments and a mentality of, “I will only use freedom of speech when it benefits me”. This can also be seen on a societal scale. For example, the American and British public is aware that their politicians lied to them about Iraq’s weapons of mass destruction. However, most people have chosen not to use their freedom of speech to hold the government accountable for countless criminal acts their governments have committed against the innocent people of Iraq.
we recently saw the Ummah hold the rulers accountable in Egypt, Jordan, Algeria and Tunisia for their continuous transgression against the Ummah. Also, during the Gaza Massacre of 2009, the Ummah in Egypt and elsewhere held the rulers accountable for allowing Israel to massacre our brothers and sisters in Palestine. And there have been many individuals and members of groups who have held their rulers accountable and faced harsh consequences, such as imprisonment, torture, and even death. These actions carry a high reward based on the following hadith:

“The master of the martyrs is Hamza ibn Abdul Mattalib, and a man who stands (in front of) an oppressive ruler and enjoins the good and forbids the evil and so is killed for it.” [Hakim]
The reason Muslims feel the need to enjoin the good and forbid the evil is because it has been placed as an obligation upon them by their Creator (swt) for which they will be immensely rewarded or punished if not undertaken, and this is why it is not subject to being discarded at the whims and desires of people.
