By Sheikh Muhammed Sahih Ibn al-Uthaimeen, translated by Dr. Saleh As-Saleh
This book discusses the fundamentals of faith, by outlining and detailing the objectives of the Islamic ‘Aqeedah. Numerous references are made to the Qur’an and authentic Ahadith, for establishing the sincere intention and worship to Allaah, liberating the mind and thought from the irrational and chaotic losses, establishing peace of mind and sound thinking, safeguarding the intentions, learning to establish a strong Ummah (community), achieving happiness in this life and the hereafter, and more.
Islam is the religion that Allah sent to Muhammad (sallallaahu alaihi wa-sallam) and made it the final and most complete religion for His slaves. Allah perfected, in this religion, the bounties that He bestowed on His salves, and accepts only Islam from them. He said, what translated means: “Muhammad (sallallaahu alaihi wa-sallam) is not the father of any man among you, but he is the Messenger of Allah, and the Last (end) of the Prophets.” [33:40], “This day, I have perfected your religion for you, completed My favor upon you, and have chosen Islam for you as your religion.” [5:3], “Truly, the religion with Allah is Islam.” [3:19] and, “And whoever seeks a religion other than Islam, it will never be accepted of him, and in the Hereafter he will be one of the losers” [3:85]
Allah obligated all mankind to follow Islam:
“Say (O Muhammad (sallallaahu alaihi wa-sallam): “O mankind! Verily, I am sent to you all as the Messenger of Allah, to Whom belongs the dominion of the heavens and the earth. There is none who has the right to be worshipped but He; It is He Who gives life and causes death. So believe in Allah and His Messenger (Muhammad (sallallaahu alaihi wa-sallam), the Prophet who can neither read nor write, who believes in Allah and His Words (this Qur’aan, the Torah and the Gospel), and follow him so that you may be guided” [7:158].
