The Just Word on the Realization of the Tawhid - Ibn Badis

The right word on the implementation of the tawhid, followed by questions & answers, by Ch. Abd Al-'Aziz Ar-Radjhi - القول السديد في بيان التوحيد (Al Qawl As-Sadid fi Bayan At-Tawhid)
The Prophet is sent to preach the Tawhid and the religion of all the Prophets and they are all sent to preach the Tawhid. The Tawhîd is to sincerely vomit his works to Allah, so that they are not impregnated with association, and to approach Allah by all the poor works that we do. Adoration is an exclusive right of Allah to his servants, and that is why He created beings.
All the actions that the Shariah commands or recommends must be dedicated exclusively to Allah, among other things, prayer, fasting, zakat, hadj, filial piety, keeping the bonds of kinship, invocation, vow, imploration of assistance to Allah, fear, ritual sacrifice (slaughter), love, fear, hope and others must be Allah. That's the Tawhîd.
Indeed, every action is vain, unless it is condemned to Allah and for the reward of the beyond. In addition, it must be consistent with the sharia.
If the person misses this principle, it will necessarily fall into the Chirk, and if the Chirk associates with adoration, it makes her vain. As if a person makes his or her ablutions, but following the exit by one of the two ways his or her purification becomes invalid. It is also the case of a monotheistic person who commits Chirk, his monotheism becomes null, and if monotheism becomes null, all works will also be.
