Saudi King Abdul Azeez (rahimahullaah) said:
Indeed, the progress and advancement of the Muslims is among those affairs we (pursue) – we call to it by the will of Allaah. [However] there cannot be advancement for the Muslims without a return to their religion, adherence to their sound creed and holding onto the Rope of Allaah (i.e. the Qur’aan and the Sunnah). The path towards this is clear and provided for the one who wants to follow it, and that is to single out Allaah in worship – to be free from shirk and bidah- and act on that which the religion has commanded us, for indeed there is no benefit in speech if not (accompanied) by action.
