An Islamic perspective: Cursing (08) Islam and Cursing, Abusive Language
Cursing is also another factor that corrupts the tongue. Whoever curses others is pushing them away from the circle of Allah's Mercy. This issue has been referred to in several verses of Noble Qur'an. Allah (SWT) has cursed many and has deprived them of his Mercy. An important case is that of Satan:
"And My curse shall be on thee till the Day of Judgment." [Sura Sad 38:78]
Those who conceal the truth are also damned in Noble Qur'an:
"Those who conceal the clear (Signs) We have sent down, and the Guidance, after We have made it clear for the people in the Book, - on them shall be Allah's curse, and the curse of those entitled to curse."[Sura Baqarah 2:159]
Those who lie were also damned as in the following verse of Noble Qur'an:
"If anyone disputes in this matter with thee, now after (full) knowledge hath come to thee, say: "Come! Let us gather together, - our sons and your sons, our women and your women, ourselves and yourselves: Then let us earnestly pray, and invoke the curse of Allah on those who lie!" [Sura Al-E-Imran 3:61]
Prophet Muhammad (saw) and Imam Ali (as) cursed several people. Imam Ali (as) has been narrated to have quoted on the authority of Prophet Muhammad (saw):
There are seven groups of people who were cursed by Allah (SWT) and His Prophet Muhammad (saw):
1- Those that change the Divine Book
2- Those who deny divine decrees
3- Those that change the Prophet's traditions
4- Those who allow to my family what Allah (SWT) has forbidden
5- Those who use their power and rule to belittle one whom Allah (SWT) has honored, and those who use their power and rule to honor one whom Allah (SWT) has debased
6- Those that make lawful what Allah (SWT) has forbidden
7 - Those those are haughty in worshipping Allah (SWT)
Prophet Muhammad (saw) said: "A believer shall not curse others."
It is even forbidden to curse animals in Islam. Overall, we can conclude that cursing men, animals and objects is forbidden, except for some instances of the infidels, the hypocrites and those who have usurped the rights of Imam Ali (as) and his descendants.
09 - Lustful Songs
The next factor that corrupts the tongue is listening or singing to lustful songs. Consider the following verses of Noble Qur'an:
"Such (is the Pilgrimage): whoever honors the sacred rites of Allah, for him it is good in the Sight of his Lord. Lawful to you (for food in Pilgrimage) are cattle, except those mentioned to you (as exception): but shun the abomination of idols, and shun the word that is false." [Sura Al- Hajj 22:30]
"Those who witness no falsehood, and, if they pass by futility, they pass by it with honorable (avoidance)." [Sura Al-Furqan 25:72]
The Arabic expressions that are translated into "shun the word that is false" and "witness no falsehood" in the above verses of Noble Qur'an have been interpreted by Shuham and Ibn Abi Amir and Abi Basir (in Kafi) and others as implying lustful songs.
However, there are two groups of traditions regarding poetry. Religious poetry is considered to be good in one group of traditions. Other traditions consider lustful poetry to be bad
