The prominent Muslim scholar, Sheikh Muhammad Iqbal Nadvi, Director and Imam of Al-Falah Islamic Center, Oakville, Ontario, Canada, states: “The basic principle that a Muslim journalist is supposed to follow is to present the truth by verifying the information to the best of his or her ability. A Muslim journalist is supposed to help spread good values and discourage evils and corruption in the society. Almighty Allah says, “And pursue not that of which thou hast no knowledge; for every act of hearing, or of seeing, or of (feeling in) the heart will be enquired into (on the Day of Reckoning).” (Al-Israa 17: 36) And He also says: “Help ye one another in righteousness and piety, but help ye not one another in sin and rancour: fear Allah: for Allah is strict in punishment.” (Al-Ma’idah 5: 2)
therefore, a Muslim journalist should never be a tool in promoting immorality or corruption of any kind. Almighty Allah says: “Those who love (to see) scandal published broadcast among the Believers, will have a grievous Penalty in this life and in the Hereafter: Allah knows, and ye know not.” (An-Nur 24: 19)
a Muslim journalist should also play a significant role in resolving conflict and patching up differences rather than aggravating them. Almighty Allah says: “The Believers are but a single Brotherhood: so make peace and reconciliation between your two (contending) brothers; and fear Allah, that ye may receive Mercy.” (Al-Hujurat 49: 10)
Keeping this in mind, a Muslim journalist could play a very important role in enjoining what is good and forbidding what is evil, and therefore converting his job to be an act of `ibadah (worship).
as far as pictures are concerned, scholars have accepted pictures describing events and incidents to help understand the situation. However, pictures showing indecency, pornography and the like MAY NOT be shown because they help spread evil and immorality.
Regarding criticizing and exposing the weaknesses of some members of the community through journalism, this depends on the maslaha or interest that is meant to be realized and the harm that could happen as a result at all. If there is no benefit or need for such criticism then it will be like backbiting. However, when there is a great need for such criticism in serving a greater cause, then it is needed, but the journalist is supposed to abide by the etiquette of giving advice in Islam. For example, if someone publishes some wrong actions of some person or an organization in order to allow people see the truth and take precaution, then this is a valid ground for pubic criticism.
The bottom line is, the journalist is to serve as a witness to the truth and not to falsehood.”
