All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
First of all, we say that it is a good pursuit that the Muslim invites to Allah and disseminates goodness.
Allah Says (what means): {And who is better in speech than one who invites to Allah and does righteousness and says, "Indeed, I am of the Muslims.} [Quran 41:33]
Al-Hassan al-Basri said:
"This is the beloved of Allah, this is the close friend of Allah, this is the chosen one of Allah, this is the most beloved of all the people of the earth to Allah. He responded to the call of Allah and called mankind to that to which he had responded, and he did righteous deeds in his response."
Anas ibn Maalik narrated that the Prophet said: "Whoever guides people to do good, he is like [i.e. he gets the same reward as] the one who does it.” [At-Tirmithi]
However, the desire for doing good and getting a reward does not justify making Da’wah with falsehood, or conveying everything that is spread.
Abu Hurayrah, narrated that the Prophet said: "It is enough a lie for a person to convey everything that he hears." [Muslim]
Therefore, a Muslim must verify what he publishes and must ascertain about the sources from which he takes information, lest he be one of the liars and one who leads people astray; in which case, he gets the sin of every person that he has misled.
Allah Says (what means): {That they may bear their own burdens in full on the Day of Resurrection and some of the burdens of those whom they misguide without knowledge. Unquestionably, evil is that which they bear.} [Quran 16:25]
Since by guiding people to do good one gets the same reward as the one who does that act of goodness, the same thing applies to the one who guides people to do evil [i.e. he gets the same sin like them].
The evidence about this is that the Prophet said: "Whoever calls to guidance, his reward will be equal to that of those who follow him without their reward being diminished in any respect, and if anyone calls to falsehood, his sin will be equal to those who follow him without their sin being diminished in any respect." [Muslim]
But if something is related to the translation, for example, which does not invalidate the truth, or renders falsehood as the truth, and does not include a lie, then this does not have any effect and there is nothing wrong in spreading it.
Allah knows best.
