قَالُواْ ٱدۡعُ لَنَا رَبَّكَ يُبَيِّن لَّنَا مَا هِيَ إِنَّ ٱلۡبَقَرَ تَشَٰبَهَ عَلَيۡنَا وَإِنَّآ إِن شَآءَ ٱللَّهُ لَمُهۡتَدُونَ ٧٠
They said, "Call upon your Lord to make clear to us what it is. Indeed, [all] cows look alike to us. And indeed we, if Allāh wills, will be guided."
Translation: Saheeh International (English)
Each word's meaning and sound
They continued in their stubbornness, telling Moses to ask Allah to further clarify the nature of the cow. They said that there were many cows fitting the description, and they could not therefore identify it, insisting that they would then, if Allah willed, be guided to the right cow for sacrifice.
