Democracy is mob-rule. In Islam there is no scope for rule by the masses. The concept of majority rule is alien to Islam.
The Qur’aan Majeed says:
“If you follow the majority on earth, they will lead you astray, away from the Path of Allah. They (the majority of people) follow nothing but baseless conjecture, and they do nothing but plunge into guesswork.”
(Surah An’aam, Aayat 116)
