At-Tawhîd (Islamic Monotheism)

At-Tawhîd (Islamic Monotheism) is to consider and believe in one God, unification of Allah is to believe in His Oneness of Rububiah (Lordship) and His Holy Names and Qualities, and to believe that He is the Owning Lord Who only deserves to be worshipped. Therefore, At-Tawhîd (Islamic Monotheism) is to perform Monotheism Allah in all what is specified for Him among all said and done adoration, and it is the basis of Islam, from which its ordinances, regulations, orders and prohibitions originated.

The Surplus of At-Tawhîd (Islamic Monotheism)

1) It is a reason for entering Paradise and get out of the Hell fire.

Allah said, “They did blaspheme who said: "Allah is Christ the son of Mary." But said Isa (Jesus): "O Children of Israel! Worship Allah, my Lord and your Lord." Whoever joins other gods with Allah, Allah will forbid him the Paradise, and the Fire will be his abode. There will for the wrongdoers be no one to help.”.

Muslim (a Hadith Scholar) narrated that the Prophet said, “He who meets with Allah not adopting a partner with Him in worship shall enter Paradise, and he who meets Him adopting a partner with Him in worship shall enter Hell Fire.” And Utban narrated that the Prophet said, “..for Allah has immuned Hell Fire from (reaching) who said, ‘La ilaha illAllah’ desiring by that only the Face of Allah (His Satisfaction).”

2) It is a condition for the acceptance of deeds, and polytheism causes them to be nullified.

Allah said, "But it has already been revealed to you, - as it was to those before you - "If you were to join (gods with Allah), truly fruitless will be your work (in life), and you will surely be in the ranks of those who lose (all spiritual good)}," and He said, “So, whoever expects to meet his Lord, let him work righteousness, and, in the worship of his Lord, admit no one as partner.”

Imam Abu Abdi-llah At-Tastari (may Allah be Merciful with him) said, “Faith is in saying, deed, intention, and Sunnah; so if there was a saying without a deed, then it is a Kufr (disbelief), or if it was a saying and a deed without an intention, then it is hypocrisy, and if it was a saying, an intention, and a deed without a Sunnah, then it is a Bid’a (novelty).”

3) It expiates sins and erases them, for Allah says in the Qudsi Hadith (Sacred Tradition which was reported by the Prophet as the Saying of Allah), “O son of Adam, were you to come to Me with sins nearly as great as the earth and were you then to face Me, ascribing no partner to Me, I would bring you forgiveness nearly as great as your sins.”
