Surah Al-Baqarah (The Cow), Verse 67

وَاِذْ قَالَ مُوْسٰی لِقَوْمِهٖۤ اِنَّ اللّٰهَ یَاْمُرُكُمْ اَنْ تَذْبَحُوْا بَقَرَةً قَالُوْۤا اَتَتَّخِذُنَا هُزُوًا قَالَ اَعُوْذُ بِاللّٰهِ اَنْ اَكُوْنَ مِنَ الْجٰهِلِیْنَ ۟

Wa iz qaala Moosaa liqawmiheee innal laaha yaamurukum an tazbahoo baqaratan qaalooo atattakhizunna huzuwan qaala a'oozu billaahi an akoona minal jaahileen

“And remember Moses said to his people: "Allah commands that ye sacrifice a heifer." They said: "Makest thou a laughing-stock of us?" He said: "Allah save me from being an ignorant (fool)!"”
