1. Don't spread rumours. Whenever you
hear something which concerns your collective life, communicate it to the
appropriate authorities so as to make them reach a correct conclusion after
(4:83) "When there comes to them some matter touching
(public) safety or fear, they divulge it, although their attachment and
obedience to the (Divine) System requires that they had only referred it to the
Rasool (central authority) or those charged with authority amongst them
(officers of the lower ranks); in case they refer it to them, the specialists
could verify and ascertain the truth."
At yet another place it is said:
(49:6) "O you who believe! If a mischief-maker comes to
you with any news, ascertain the truth, lest you should harm people unknowingly,
and afterwards have to feel ashamed for what you have done."
2. When you hear a rumour against somebody, your first reaction
ought to be that it is a calumny. In Surah "An-Noor" (24th Chapter of the Quran)
an event has been mentioned concerning a noble, chaste lady, about whom somebody
started a rumour which got spread in the society.
(24:12) "When you heard it, why did you not react with a
favourable view and declare it as a clear calumny Why did not believers __ men
and women __ when they heard of the affair, thought good of your own fold and
said: It is a manifest calumny."
It was further said:
you received it on your tongues and spoke with your mouths that of which you had
no knowledge, and you deemed it a trifle, while with Allah it was serious. And
why did you not, when you heard it, say: It beseems us not to talk of it. Glory
be to Thee! This is a great calumny"
