(Al-Baqara) 2 : 70
قَالُوا ادْعُ لَنَا رَبَّكَ يُبَيِّنْ لَنَا مَا هِيَ إِنَّ الْبَقَرَ تَشَابَهَ عَلَيْنَا وَإِنَّا إِنْ شَاءَ اللَّهُ لَمُهْتَدُونَ
They said: “Appeal to your Lord for us to explain to us which it is; indeed, all cows seem alike to us, and indeed we will become guided if Lord Allah wishes”.
