Muslim men and Muslim women are obliged to follow the commands of Allaah and His Messenger, no matter how difficult that may be for people and without feeling shy of other people. The believer who is sincere in his faith is the one who is sincere in carrying out his duty towards his Lord and obeying His commands and avoiding that which He has forbidden. No believer, man or woman, has the right to hesitate or delay with regard to commands; rather he or she should hear and obey immediately, in accordance with words of Allaah (interpretation of the meaning):
“It is not for a believer, man or woman, when Allaah and His Messenger have decreed a matter that they should have any option in their decision” [al-Ahzaab 33:36]
This is the case with the believers who are praised by their Lord in the aayah (interpretation of the meaning):
“The only saying of the faithful believers, when they are called to Allaah (His Words, the Qur’aan) and His Messenger, to judge between them, is that they say: “We hear and we obey.” And such are the successful (who will live forever in Paradise).
And whosoever obeys Allaah and His Messenger , fears Allaah, and keeps his duty (to Him), such are the successful” [al-Noor 24:51-52]
Moreover, the Muslim should not look at how small or great the sin is, rather he should look at the greatness and might of the One Whom he is disobeying, for He is the Most Great, the Most High; He is Mighty in strength and Severe in punishment, and His punishment is severe and painful and humiliating. If He exacts vengeance on those who disobey Him, then utter destruction will be their fate. Allaah says (interpretation of the meaning):
“Such is the Seizure of your Lord when He seizes the (population of) towns while they are doing wrong. Verily, His Seizure is painful (and) severe.
Indeed in that (there) is a sure lesson for those who fear the torment of the Hereafter. That is a Day whereon mankind will be gathered together, and that is a Day when all (the dwellers of the heavens and the earth) will be present” [Hood 11:102-103]
A sin may appear insignificant in the eyes of a person when before Allaah it is serious, as Allaah says (interpretation of the meaning):
“you counted it a little thing, while with Allaah it was very great”
[al-Noor 24:15]
“Let there arise out of you a group of people inviting to all that is good (Islam), enjoining Al-Ma‘roof (i.e. Islamic Monotheism and all that Islam orders one to do) and forbidding Al-Munkar (polytheism and disbelief and all that Islam has forbidden). And it is they who are the successful” [Aal ‘Imraan 3:104]
Enjoining what is good (al-ma’roof) and forbidding what is evil (al-munkar) is one of the most important Islamic duties, indeed it is the noblest and most sublime. This is the task of the Prophets and Messengers (peace be upon them all), as Allaah says (interpretation of the meaning):
“Messengers as bearers of good news as well as of warning in order that mankind should have no plea against Allaah after the (coming of) Messengers” [al-Nisaa’ 4:165]
Allaah has made the Muslim ummah the best nation ever raised up for mankind, in order to do this important task, as Allaah says (interpretation of the meaning):
“You (true believers in Islamic Monotheism, and real followers of Prophet Muhammad and his Sunnah) are the best of peoples ever raised up for mankind; you enjoin Al-Ma‘roof (i.e. Islamic Monotheism and all that Islam has ordained) and forbid Al-Munkar (polytheism, disbelief and all that Islam has forbidden), and you believe in Allaah” [Aal ‘Imraan 3:110]
If the ummah fails to do its duty of enjoining what is good and forbidding what is evil, wrongdoing and corruption will spread throughout the ummah, and it will deserve the curse of Allaah. For Allaah cursed those among the Children of Israel who disbelieved because they failed in this important duty. Allaah says (interpretation of the meaning):
“Those among the Children of Israel who disbelieved were cursed by the tongue of Dawood (David) and ‘Eesa (Jesus), son of Maryam (Mary). That was because they disobeyed (Allaah and the Messengers) and were ever transgressing beyond bounds.
They used not to forbid one another from Al-Munkar (wrong, evildoing, sins, polytheism, disbelief) which they committed. Vile indeed was what they used to do [al-Maa’idah 5:78]
Enjoining what is good and forbidding what is evil is a mission which will never end until the Hour begins. It is obligatory upon all the ummah, rulers and subjects, men and women, each according to his or her circumstances. The Prophet (peace and blessings of Allaah be upon him) said: “Whoever among you sees an evil action, let him change it with his hand [by taking action]; and if he cannot, then with his tongue [by speaking out]; and if he cannot, then with his heart [by feeling that it is wrong] – and that is the weakest of faith.” (Narrated by Muslim, 49)
