Quran 6:22 from Surah Al-An'aam on Divine Marvels.
وَيَوۡمَ نَحۡشُرُهُمۡ جَمِيعٗا ثُمَّ نَقُولُ لِلَّذِينَ أَشۡرَكُوٓاْ أَيۡنَ شُرَكَآؤُكُمُ ٱلَّذِينَ كُنتُمۡ تَزۡعُمُونَ
English translation: And (the) Day We will gather them all then We will say to those who associated others with Allah Where (are) your partners those whom you used to claim
Transliteration: wayawma nahshuruhum jami'an thumma naqulu lilladhina ashraku ayna shurakaukumu alladhina kuntum taz'umuna
