The servant does not escape the punishment of Allah unless he believes in Allah (Mighty and Majestic) and His Messenger Muhammad (peace and blessings be upon him) together.

The Shaykh : In this hadith, there is a reference to a fundamental Islamic belief. I believe that some of the youth who have strayed from their religion need to hear a hadith like this. It is common today for there to be philosophers in Europe and America who believe that this universe has a Creator. I do not say, as some people do, that they believe this universe has a deity, because many Muslims today do not even know what deity (ilahiyah) means, let alone those polytheists who disbelieve in Allah and His Messenger. I want to say that the existence of such disbelievers who have used their intellect to reach the belief that this universe has a Creator—this alone is not enough for its holder to be saved from Allah on the Day of Resurrection. This is for reasons, one of which I hinted at earlier: belief in Allah (Mighty and Majestic) is of no benefit if it is limited to believing that He is the Creator of this universe. This belief is, in reality, like a compulsory matter that a person feels by his innate disposition (fitrah). However, the implications of this belief—believing in this specific Creatorship belonging to Allah (Mighty and Majestic), which includes submission to Him, deifying Him, and worshipping Him alone, without any other created being, no matter how great or exalted—this deity (ilahiyah) that befits Allah (Mighty and Majestic) must be added to the belief in His Creatorship (Blessed and Exalted is He). When the polytheists disbelieved in this, they were declared disbelievers, fought, and killed. Therefore, he (peace be upon him) said: Rather, they must testify that there is no deity but Allah. I do not want to delve into this testimony, its meaning, and its implications regarding belief in the oneness of worship (tawhid al-uluhiyyah), the oneness of attributes, and the oneness of names, as we have spoken about this much and often. I only wanted to mention that the youth should not be deceived by these philosophers and the like of them who believe that Allah (Mighty and Majestic) is unique in the attribute of creation and nothing else. This does not benefit them in any way.
Especially since, even if their belief in the Creatorship of Allah (Mighty and Majestic) were joined with belief in His deity (ilahiyah) and all the names and attributes, that still would not be sufficient for them and would not benefit them in any way, until they believe in him (peace and blessings be upon him) as a Prophet and Messenger.
This is the meaning of the testimony: Therefore, it came in the authentic hadith in Muslim and others that he (peace and blessings be upon him) said: Therefore, there is a very great obligation upon the Muslims, but unfortunately, the Muslims are preoccupied with themselves. It is their obligation to convey this call, the call of the Messenger of Allah (peace and blessings be upon him and his family), to those people, the Christians, the Jews, and the like of them from the polytheists, so that they believe in Allah and His Messenger. This is out of compassion and mercy for them, because the one who strives to have all of humanity enter Paradise is compassionate and merciful, unlike the one who does not care whether people enter Paradise or plunge into the Fire.
