And [recall] when We made an appointment with Moses for forty nights. Then you took [for worship] the calf after him, while you were wrongdoers.

And [recall] when We gave Moses the Scripture and criterion that perhaps you would be guided.

And [recall] when Moses said to his people, "O my people, indeed you have wronged yourselves by your taking of the calf [for worship]. So repent to your Creator and kill yourselves. That is best for [all of] you in the sight of your Creator." Then He accepted your repentance; indeed, He is the Accepting of repentance, the Merciful.

And [recall] when you said, "O Moses, we will never believe you until we see Allah outright"; so the thunderbolt took you while you were looking on.

And [recall] when Moses said to his people, "Indeed, Allah commands you to slaughter a cow." They said, "Do you take us in ridicule?" He said, "I seek refuge in Allah from being among the ignorant."

They said, "Call upon your Lord to make clear to us what it is." [Moses] said, "[Allah] says, 'It is a cow which is neither old nor virgin, but median between that,' so do what you are commanded."
