Cursing in Islam is prohibited

Muslims should neither curse nor imprecate each other with words such as, ‘May the Curse of Allah be upon you,’ or ‘I wish you to burn in Hell-fire,’ etc.Narrated Samurah Ibn Jundub (radhi allahu anhu), ‘Allah’s Messenger (sallallahu aliahi wa-sallam) said,

‘Do not curse one another, invoking curse of Allah or Wrath of Allah or the fire of Hell’ [Abu Dawood, at-Tirmidhee]

To curse a Muslim is akin to killing him. Allah’s Messenger (sallallahu aliahi wa-sallam) said, Cursing a believer is like murdering him.’ [Agreed upon]

The act of cursing is such that one who does it can himself become a recipient of it.

Narrated Abu Darda (radhi allahu anhu),

Allah’s Messenger (sallallahu aliahi wa-sallam) said, When a person curses (La’nah; to ask that something be deprived of Allah’s Mercy) somebody or something, the curse goes up to the heaven and the gates of the heaven are closed. Then it comes down to the earth and its gates are closed. Then it turns right and left, and if it does not find an entrance to go anywhere, it returns to the person or thing that was cursed, if he or it deserves to be cursed; otherwise, it returns to the person, who uttered it.’ [Abu Dawood] Allah’s Messenger (sallallahu aliahi wa-sallam) also warned, ‘Those who frequently resort to cursing would neither be accepted as witnesses nor as intercessors on the Day of Resurrection’ [Saheeh Muslim]

It is not allowed to curse, disgrace or humiliate even a sinner because in doing so, one helps the Shaytan, who is avowed to disgrace and humiliate Muslims before Allah. Narrated Abu Hurayrah (radhi allahu anhu), ‘A drunkard was brought to the Prophet (sallallahu aliahi wa-sallam). He (r) said, ‘Give him a beating.’ Then some beat him with their hands, some with their shoes, and some with (a folded) piece of cloth. When he left, someone said to him, ‘May Allah disgrace you!‘ The Prophet (sallallahu aliahi wa-sallam) said, ‘Do not help

Shaytan overcome him by uttering such words’ [Saheeh al-Bukharee]

Moreover, it is incorrect to curse a sinner because perhaps, the person may have sought Istagfar (seek forgiveness for one’s sins) and Allah, the All-Forgiving, may have forgiven the person for his transgression. It is related in Saheeh Muslim that during the time of Allah’s Messenger (sallallahu aliahi wa-sallam), when a woman was being punished for the sin of adultery, her blood spurted upon Khalid Ibn Waleed (radhi allahu anhu), who swore at her. Thereupon, the Prophet (sallallahu aliahi wa-sallam) said, ‘Khalid, be gentle. By Him, in Whose Hand is my life, she has made such a repentance that even if a wrongful tax collector were to repent, he would have been forgiven.’ He (sallallahu aliahi wa-sallam) then prayed over her and she was buried. Therefore, the right conduct would be to pray for his or her guidance and refrain from any critique, cursing or humiliation.

Even the deceased Muslims should not be censured or condemned for their wrongdoings, for, they have reached their end and they are receiving the return of their deeds in the Hereafter. Aa’isha (radhi allahu anha) narrated, ‘The Messenger of Allah (sallallahu aliahi wa-sallam) said, ‘Do not abuse the dead, because they have attained that which they had forwarded (i.e., their deeds, good or bad).’ [Saheeh al-Bukharee]

`Umar ibn Khattab (Allah be well pleased with him) said:

“As we were sitting one day before the Messenger of Allah (peace and blessings be upon him), a man suddenly appeared. He wore pure white clothes and his hair was dark black-yet there were no signs of travel on him, and none of us knew him.

He came and sat down in front of the Prophet (peace and blessings be upon him), placing his knees against his, and his hands on his thighs. He said, “O Muhammad! Tell me about Islam.”

The Messenger of Allah (peace and blessings be upon him) replied, “Islam is to bear witness that there is no god but Allah and Muhammad is the Messenger of Allah; and to perform the prayer; pay zakat; fast Ramadan; and to perform Hajj to the House if you are able.”

The man said, “You have spoken the truth,” and we were surprised that he asked and then confirmed the answer.

Then, he asked, “Tell me about belief (iman).”

The Prophet (peace and blessings be upon him) replied, “It is to believe in Allah; His Angels; His Books; His Messengers; the Last Day; and in destiny-its good and bad.”

The man said, “You have spoken the truth. Now, tell me about spiritual excellence (ihsan).”

The Prophet (peace and blessings be upon him) replied, “It is to serve Allah as though you behold Him; and if you don’t behold him, (know that) He surely sees you.”

“Now, tell me of the Last Hour,” asked the man.

The Prophet (peace and blessings be upon him) replied, “The one asked knows no more of it than the one asking.”

“Then tell me about its signs,” said the man.

The Prophet (peace and blessings be upon him) replied, “That slave women give birth to their mistresses; and that you see barefoot, unclothed, beginning shepherds competing in the construction of tall buildings.”

Then the visitor left, and I waited a long time. Then the Prophet (peace and blessings be upon him) asked me, “Do you know, Umar, who the questioner was?”

I replied, “Allah and His Messenger know best.”

He said (Allah bless him and give him peace), “It was Jibril. He came to you to teach you your religion.”

[Sahih Muslim]

LAST SERMON OF PROPHET MUHAMMAD(PEACE BE UPON HIM)

"O People, lend me an attentive ear, for I know not whether after this year, I shall ever be amongst you again. Therefore listen to what I am saying to you very carefully and TAKE THESE WORDS TO THOSE WHO COULD NOT BE PRESENT HERE TODAY.

O People, just as you regard this month, this day, this city as Sacred, so regard the life and property of every Muslim as a sacred trust. Return the goods entrusted to you to their rightful owners. Hurt no one so that no one may hurt you. Remember that you will indeed meet your LORD, and that HE will indeed reckon your deeds. ALLAH has forbidden you to take usury (interest), therefore all interest obligation shall henceforth be waived. Your capital, however, is yours to keep. You will neither inflict nor suffer any inequity. Allah has Judged that there shall be no interest and that all the interest due to Abbas ibn 'Abd'al Muttalib (Prophet's uncle) shall henceforth be waived...

Beware of Satan, for the safety of your religion. He has lost all hope that he will ever be able to lead you astray in big things, so beware of following him in small things.

O People, it is true that you have certain rights with regard to your women, but they also have rights over you. Remember that you have taken them as your wives only under Allah's trust and with His permission. If they abide by your right then to them belongs the right to be fed and clothed in kindness. Do treat your women well and be kind to them for they are your partners and committed helpers. And it is your right that they do not make friends with any one of whom you do not approve, as well as never to be unchaste.

O People, listen to me in earnest, worship ALLAH, say your five daily prayers (Salah), fast during the month of Ramadan, and give your wealth in Zakat. Perform Hajj if you can afford to.

All mankind is from Adam and Eve, an Arab has no superiority over a non-Arab nor a non-Arab has any superiority over an Arab; also a white has no superiority over black nor a black has any superiority over white except by piety and good action. Learn that every Muslim is a brother to every Muslim and that the Muslims constitute one brotherhood. Nothing shall be legitimate to a Muslim which belongs to a fellow Muslim unless it was given freely and willingly. Do not, therefore, do injustice to yourselves.

Remember, one day you will appear before ALLAH and answer your deeds. So beware, do not stray from the path of righteousness after I am gone.

O People, NO PROPHET OR APOSTLE WILL COME AFTER ME AND NO NEW FAITH WILL BE BORN. Reason well, therefore, O People, and understand words which I convey to you. I leave behind me two things, the QURAN and my example, the SUNNAH and if you follow these you will never go astray.

All those who listen to me shall pass on my words to others and those to others again; and may the last ones understand my words better than those who listen to me directly. Be my witness, O ALLAH, that I have conveyed your message to your people".
