This is a book in Amharic entitled One Message. Since the beginning of 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) along with the laws Allah has prescribed to regulate human lives, both personally and in their interactions with others, is the Message brought by all the prophets and Messengers, to all nations. Down through the ages, the Messages of the earlier prophets and Messengers were distorted or concealed, until the truth was corrupted or lost. Finally, Allah sent His last Messenger, Muhammad (blessings and peace be upon him) with the ultimate Message addressed to all of humanity, the Message of Islam, and Allah Himself guaranteed to preserve it until the end of time.
