They said, "Call upon your Lord to show us what is her (2:69)

﴿قَالُوا ادْعُ لَنَا رَبَّكَ يُبَيِّن لَّنَا مَا لَوْنُهَا ۚ قَالَ إِنَّهُ يَقُولُ إِنَّهَا بَقَرَةٌ صَفْرَاءُ فَاقِعٌ لَّوْنُهَا تَسُرُّ النَّاظِرِينَ﴾
[ البقرة: 69]

2:69 They said, "Call upon your Lord to show us what is her color." He said, "He says, 'It is a yellow cow, bright in color - pleasing to the observers.' "

They continued debating and being stubborn, telling Moses ( peace be upon him ) to call on his Lord to make clear to them the colour of the cow.
Moses told them that Allah said that it was a yellow cow, with a very strong colour, which was pleasing to everyone who saw it.

They said, "Call upon your Lord for us to make plain to us its colour." He said, "He says, 'It is a yellow cow, bright in its colour, pleasing to the beholders.' "
