Is merely denying that the word "wateen" mentioned in the Holy Quran is an artery, and being ignorant of its existence in the Quran, considered an act of disbelief that invalidates good deeds and necessitates performing ghusl and reciting the Two Testimonies anew?

We congratulate the questioner on their steadfastness and inform them that what was mentioned does not lead to disbelief, because their ignorance of the word's presence in the Quran or its meaning does not result in apostasy or a depreciation of the Quran. Therefore, they are not required to pronounce the Shahada or perform ghusl, especially since their intention was not mockery. Scholars have stipulated that for disbelief to be established, ignorance must be absent, citing the words of the people of Moses: "Make for us a god just as they have gods," and Moses' response: "Indeed, you are a people who are ignorant." They also cite the Sahaba's request to the Prophet, peace and blessings be upon him: "Make for us a Dhat Anwat," and the hadith of the man who ordered his body to be burned and scattered in the wind out of fear of Allah, and he was forgiven.
