Any attempt to disrupt the polls or prevent the people from casting their votes is a major sin
In a recently issued fatwa, Dar al-Ifta confirmed that the casting of votes is a kind of testimony. The fatwa stressed that it is impermissible to prevent a witness from giving his testimony. With regards to the referendum, any attempt to prevent the people from casting their votes poses harm to the entire society.
The fatwa said that those who plan to prevent citizens from reaching polling stations in an attempt to undermine the voting process, are considered sinners. They are deemed propagators of chaos and corruption who help in concealing testimony and come under the words of Allah "his heart is indeed sinful". It added that the crime of those who engage in acts of destruction and corruption is greater because they destabilize the society and threaten people’s lives and property. If they persist in such acts, they come under the ruling of hiraba (armed robbery) of which God says, "Indeed, the penalty for those who wage war against Allah and His Messenger and strive upon earth [to cause] corruption is none but that they be killed or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land. That is for them a disgrace in this world; and for them in the Hereafter is a great punishment" (Qur'an 5:33)
