A true Muslim, as the infallible Prophet (peace and blessings be upon him) said, can never be a slanderer, a curser, an indecent, or an abusive person. Moreover, since such insults and accusations are prohibited when uttered by the tongue, they are more blameworthy when written, especially on the Internet because there they can be read and quickly spread by so many people. Muslims should follow Islamic teachings in dealing with each other and also when dealing with those adopting different beliefs, for Islam is free from such insults and abuses.
Concerning this issue, the prominent Muslim scholar Sheikh Ahmad Bin Hamad Al-Khalili, the Grand Mufti of Oman states the following: The Internet is a favor that Allah Almighty has bestowed on us, for which we should show gratitude. One of the ways of showing gratitude for it is using it in a way that pleases Allah Almighty. As for what you have mentioned concerning the exchange of accusations and insults, it is, by all means, contradictory to our true religion. The true Muslim is the one who avoids harming Muslims with his tongue and hands. Since one is responsible for what one says, one is also responsible for what one writes. The responsibility of writing may even be much more grievous than that resulting from speech, for the latter is uttered in a certain moment after which no effect may remain, but this is not the case in writing. The impact of writing can be stretched out to every reader of such material, especially when using such modern devices that spread written material and can even be used in transmitting it audibly. This, of course, would multiply one’s sin if these devices were used in something not satisfactory to Allah Almighty.
In this connection it is worth quoting the Prophetic hadith that reads: “One may utter a word without thinking whether it is right or wrong, which causes him to sink in the Hellfire to a distance farther than that which is between the east and the west.” The Prophet (peace and blessings be upon him) also said, “One may utter a word which pleases Allah without thinking it could reach what it has reached, and with which Allah destines for him to be in Allah’s pleasure until he meets Him (on the Day of Judgment). And (on the contrary) one may utter a word which displeases Allah without thinking it could reach what it has reached, and with which Allah destines for him to be under Allah’s wrath until he meets Him.” Thus, one should fear Allah concerning what he utters or writes. The following poetic lines may be useful in this concern: In people’s defects don’t indulge. If you have a tongue, People also have one
In conclusion, exchanging accusations in the way mentioned is not by any means to the benefit of our nation;, it rather adds to the break in the nation’s body and finally leads to its full dispersion. This, of course, does not please Allah Almighty, so we ask Him to protect us from such evils.
