In the following some verses narrating when prophet Moses peace be upon him left his people (Jews of that time) for forty nights and returned to find them worshiping a statue of a calf so Moses invited them to repent and also a punishment was carried out by their own prophet. 

2:51 Al-Baqara
‎وَإِذْ وَاعَدْنَا مُوسَىٰ أَرْبَعِينَ لَيْلَةً ثُمَّ اتَّخَذْتُمُ الْعِجْلَ مِنْ بَعْدِهِ وَأَنْتُمْ ظَالِمُونَ
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.
2:52 Al-Baqara
‎ثُمَّ عَفَوْنَا عَنْكُمْ مِنْ بَعْدِ ذَٰلِكَ لَعَلَّكُمْ تَشْكُرُونَ
Then We forgave you after that so perhaps you would be grateful.
2:53 Al-Baqara
‎وَإِذْ آتَيْنَا مُوسَى الْكِتَابَ وَالْفُرْقَانَ لَعَلَّكُمْ تَهْتَدُونَ
And [recall] when We gave Moses the Scripture and criterion that perhaps you would be guided.
2:54 Al-Baqara
‎وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِ يَا قَوْمِ إِنَّكُمْ ظَلَمْتُمْ أَنْفُسَكُمْ بِاتِّخَاذِكُمُ الْعِجْلَ فَتُوبُوا إِلَىٰ بَارِئِكُمْ فَاقْتُلُوا أَنْفُسَكُمْ ذَٰلِكُمْ خَيْرٌ لَكُمْ عِنْدَ بَارِئِكُمْ فَتَابَ عَلَيْكُمْ ۚ إِنَّهُ هُوَ التَّوَّابُ الرَّحِيمُ
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.
 20:85 Taa-Haa
  ‎قَالَ فَإِنَّا قَدْ فَتَنَّا قَوْمَكَ مِنْ بَعْدِكَ وَأَضَلَّهُمُ السَّامِرِيُّ 
 [Allah] said, "But indeed, We have tried your people after you [departed], and the Samiri has led them astray."  
20:86 Taa-Haa  ‎
‎فَرَجَعَ مُوسَىٰ إِلَىٰ قَوْمِهِ غَضْبَانَ أَسِفًا ۚ قَالَ يَا قَوْمِ أَلَمْ يَعِدْكُمْ رَبُّكُمْ وَعْدًا حَسَنًا ۚ أَفَطَالَ عَلَيْكُمُ الْعَهْدُ أَمْ أَرَدْتُمْ أَنْ يَحِلَّ عَلَيْكُمْ غَضَبٌ مِنْ رَبِّكُمْ فَأَخْلَفْتُمْ مَوْعِدِي  
So Moses returned to his people, angry and grieved. He said, "O my people, did your Lord not make you a good promise? Then, was the time [of its fulfillment] too long for you, or did you wish that wrath from your Lord descend upon you, so you broke your promise [of obedience] to me?"  20:87 Taa-Haa  ‎
‎قَالُوا مَا أَخْلَفْنَا مَوْعِدَكَ بِمَلْكِنَا وَلَٰكِنَّا حُمِّلْنَا أَوْزَارًا مِنْ زِينَةِ الْقَوْمِ فَقَذَفْنَاهَا فَكَذَٰلِكَ أَلْقَى السَّامِرِيُّ  
They said, "We did not break our promise to you by our will, but we were made to carry burdens from the ornaments of the people [of Pharaoh], so we threw them [into the fire], and thus did the Samiri throw."  
20:88 Taa-Haa  ‎
‎فَأَخْرَجَ لَهُمْ عِجْلًا جَسَدًا لَهُ خُوَارٌ فَقَالُوا هَٰذَا إِلَٰهُكُمْ وَإِلَٰهُ مُوسَىٰ فَنَسِيَ  
And he extracted for them [the statue of] a calf which had a lowing sound, and they said, "This is your god and the god of Moses, but he forgot."  
20:89 Taa-Haa  ‎
‎أَفَلَا يَرَوْنَ أَلَّا يَرْجِعُ إِلَيْهِمْ قَوْلًا وَلَا يَمْلِكُ لَهُمْ ضَرًّا وَلَا نَفْعًا  
Did they not see that it could not return to them any speech and that it did not possess for them any harm or benefit?  20:90 Taa-Haa  ‎
‎وَلَقَدْ قَالَ لَهُمْ هَارُونُ مِنْ قَبْلُ يَا قَوْمِ إِنَّمَا فُتِنْتُمْ بِهِ ۖ وَإِنَّ رَبَّكُمُ الرَّحْمَٰنُ فَاتَّبِعُونِي وَأَطِيعُوا أَمْرِي  
And Aaron had already told them before [the return of Moses], "O my people, you are only being tested by it, and indeed, your Lord is the Most Merciful, so follow me and obey my order."  
20:91 Taa-haa
  ‎قَالُوا لَنْ نَبْرَحَ عَلَيْهِ عَاكِفِينَ حَتَّىٰ يَرْجِعَ إِلَيْنَا مُوسَىٰ  They said, "We will never cease being devoted to the calf until Moses returns to us."  
20:92 Taa-Haa  ‎
‎قَالَ يَا هَارُونُ مَا مَنَعَكَ إِذْ رَأَيْتَهُمْ ضَلُّوا  [Moses] said, "O Aaron, what prevented you, when you saw them going astray,  
20:93 Taa-Haa  ‎
‎أَلَّا تَتَّبِعَنِ ۖ أَفَعَصَيْتَ أَمْرِي  
Don’t you follow me? Have you disobeyed my order?"  
20:94 Taa-Haa
  ‎قَالَ يَا ابْنَ أُمَّ لَا تَأْخُذْ بِلِحْيَتِي وَلَا بِرَأْسِي ۖ إِنِّي خَشِيتُ أَنْ تَقُولَ فَرَّقْتَ بَيْنَ بَنِي إِسْرَائِيلَ وَلَمْ تَرْقُبْ قَوْلِي  [Aaron] said, "O son of my mother, do not seize [me] by my beard or by my head. Indeed, I feared that you would say, 'You caused division among the Children of Israel, and you did not observe [or await] my word.' "  
20:95 Taa-Haa
 ‎قَالَ فَمَا خَطْبُكَ يَا سَامِرِيُّ 
[Moses] said, "And what is your case, O Samiri?"  
20:96 Taa-Haa  ‎
‎قَالَ بَصُرْتُ بِمَا لَمْ يَبْصُرُوا بِهِ فَقَبَضْتُ قَبْضَةً مِنْ أَثَرِ الرَّسُولِ فَنَبَذْتُهَا وَكَذَٰلِكَ سَوَّلَتْ لِي نَفْسِي  
He said, "I saw what they did not see, so I took a handful [of dust] from the track of the messenger and threw it, and thus did my soul entice me."  
20:97 Taa-haa
 ‎قَالَ فَاذْهَبْ فَإِنَّ لَكَ فِي الْحَيَاةِ أَنْ تَقُولَ لَا مِسَاسَ ۖ وَإِنَّ لَكَ مَوْعِدًا لَنْ تُخْلَفَهُ ۖ وَانْظُرْ إِلَىٰ إِلَٰهِكَ الَّذِي ظَلْتَ عَلَيْهِ عَاكِفًا ۖ لَنُحَرِّقَنَّهُ ثُمَّ لَنَنْسِفَنَّهُ فِي الْيَمِّ نَسْفًا  [Moses] said, "Then go. And indeed, it is [decreed] for you in [this] life to say, 'No contact.' And indeed, you have an appointment [in the Hereafter] you will not fail to keep. And look at your 'god' to which you remained devoted. We will surely burn it and blow it into the sea with a blast.  
20:98 Taa-Haa
 ‎إِنَّمَا إِلَٰهُكُمُ اللَّهُ الَّذِي لَا إِلَٰهَ إِلَّا هُوَ ۚ وَسِعَ كُلَّ شَيْءٍ عِلْمًا  
Your god is only Allah, except for whom there is no deity. He has encompassed all things in knowledge."
