Quran 2:69 Al-Baqarah, ayah 69 of 286

قَالُوا۟ ٱدْعُ لَنَا رَبَّكَ يُبَيِّن لَّنَا مَا لَوْنُهَا ۚ قَالَ إِنَّهُۥ يَقُولُ إِنَّهَا بَقَرَةٌ صَفْرَآءُ فَاقِعٌ لَّوْنُهَا تَسُرُّ ٱلنَّـٰظِرِينَ ۝٦٩

2:69 They said: Pray for us unto thy Lord that He make clear to us of what colour she is. (Moses) answered: Lo! He saith: Verily she is a yellow cow. Bright is her colour, gladdening beholders.
