Quran 2:23 — The Heifer (Al-Baqarah)

وَإِن كُنتُم فى رَيبٍ مِمّا نَزَّلنا عَلىٰ عَبدِنا فَأتوا بِسورَةٍ مِن مِثلِهِ وَادعوا شُهَداءَكُم مِن دونِ اللَّهِ إِن كُنتُم صٰدِقينَ

If you have any doubt regarding what we revealed to our servant*, then produce one sura like these, and call upon your own witnesses against GOD, if you are truthful.

[2:22] The One who made the earth habitable for you, and the sky a structure. He sends down from the sky water, to produce all kinds of fruits for your sustenance. You shall not set up idols to rival GOD, now that you know.

[2:24] If you cannot do this—and you can never do this—then beware of the Hellfire, whose fuel is people and rocks; it awaits the disbelievers.
