Demonstrations and Protests are satanic innovations—by Shaikh Zayd Bin Haadi (rahimahullaah)
In The Name of Allaah, The Most Merciful, The Bestower of Mercy
The end results of protests (or demonstrations): Carnage, destruction, wastage of wealth and time and and terrorising those living in peace. And how many disadvantages are there in (that)! It is enough to be considered something sinister due to the fact that the Noble Messengers and the Great Prophets who were put to trial and harmed by their people and those who believed in them did not hold protests (or demonstrations), and neither did they engage in plotting to cause explosions nor committing suicide; rather Islaam has forbidden all of that.
Those who call to protests (or demonstrations) and hold that there is success in it, they are mistaken and they have missed the correct path. Rectification of the affairs can only be by way of the Book and The Sunnah in accordance with the understanding of those scholars who are firmly grounded in knowledge. So whoever calls the people to this chaos, then indeed he has brought about a means to corrupting the land and the slaves, and what has happened before and at present is a witness to that.
Therefore, we warn the students of knowledge that they are not persuaded by the speech of those who allow protests (or demonstrations) and hold that peaceful demonstrations are permissible, as they say and categorise it into this categorisation -without proofs and concrete evidence from the Book and the Sunnah, neither from the actions of the Messenger and the Noble Sahaabah nor from the Notable Imaams; rather the verdict on protests (or demonstrations) is only what has been stated earlier and as well as what has been written by other than myself [i.e. protests (or demonstrations) are not permissible]
