From time immemorial, the Devil has been launching his attacks against people. But from that time, Allah has been sending His Message to humankind, reminding them of the purpose for which they were created, namely, to worship Him alone. This message of tawheed (the Islamic concept of monotheism), accompanied by laws which regulate human life on the individual and social level, is the Message brought by all the prophets and Messengers, down throughout the ages, to all nations.
