In a lecture few years ago Yasir Qadhi, the Dean of Academic Affairs at AlMaghrib Institute in Houston, Texas, said the following:
“This is the precise definition of shirk [polytheism] to make a partner along with Allah, Glorified and Exalted be He [GEBH]. And we realize that obviously shirk [polytheism] that is the opposite of tawhid [monotheism] must by necessity and by definition be the the most evil of all evils as Jews and Christians are mushrikoon [polytheists] in our perspective of tawhid [monotheism] as we have studied can understand how, and only the Muslims are upon tawhid [monotheism]. And it is also the ame reason, or the same principle of tawhid [monotheism] which is the first obligation upon every single human being, that he bears witness and he testifies that there is no deity worthy of worship except Allah GEBH. And it is because of this same principle of tawhid [monotheism] that the Prophet, peace be upon him, has been commanded to do jihad. Jihad is a means and not a goal of itself. It is a means to establish tawhid [monotheism] on the land. أمرت أن أقاتل الناس حتى يشهدوا أن لا إله إلا الله I have been commanded to fight the people until they testify لا إله إلا الله there is no God but Allah. So the whole reason why Allah GEBH has created us sent the prophets and revealed the books and differentiated us based upon this principle and allowed for jihad, is the basis and is the principle of tawhid [monotheism]. The life and property of a mushrik [polytheist, also identified as Christian] holds no value in the state of jihad. Make no respect. Notice that I said in the state of jihad, not at all times and places. The life and property of a mushrik becomes ‘halal’ [permissible] while in a state of jihad. The prophet, peace be upon him, said, and I quote the hadith before, ‘I have been commanded to fight the people until they say: ‘There is no god but Allah’ [Islamic creed declaring belief in the tawhid [monotheism], and when they say ‘There is no god but Allah’ [meaning accepting Islam], he went on, when they say ‘There is no god but Allah’ [meaning accepting Islam], their life and property become protected for me. Which means if they don’t say ‘There is no god but Allah’ [meaning accepting Islam] their life and property are halal [permissible] for the Muslims. So the Christians do commit shirk [polytheism], they are ‘kuffar’ [disbelievers] and they are mushrikoon [polytheists]. The mushrikoon [polytheists] are najis [impure, filth], they are filthy. Najasa [impurity, filth]. They are filthy, a spiritual filthiness which can only be purified by the purity of monotheism [tawhid]. Allah calls the mushrikoon [polytheists] najis [filthy] which is a very evil thing. When Allah Himself says the mushrikoon [polytheists] are najis [impure, filth], Allah is calling them najis [impure, filth], they are najasa [impurity], a filthy, impure, dirty substance.”

On July 3, 2013 Yasir Qadhi published a “Clarification and Notice” in which he wrote among other things the following:
“Never have I claimed that Christians need to be prevented from practicing Christianity, or that they are filthy. This is truly a preposterous claim, as even the most basic exposure to Islamic law would demonstrate that non-Muslims are allowed to worship according to their doctrines in an Islamic state. Therefore (and I have made this point many times in my lectures), if this is the case in an ideal and theoretical ‘Islamic state’, how can anyone claim that Muslims want to ban Christianity in a non-Islamic land?”
