1. 12:25 وَٱسْتَبَقَا ٱلْبَابَ وَقَدَّتْ قَمِيصَهُۥ مِن دُبُرٍ وَأَلْفَيَا سَيِّدَهَا لَدَا ٱلْبَابِ قَالَتْ مَا جَزَآءُ مَنْ أَرَادَ بِأَهْلِكَ سُوٓءًا إِلَّآ أَن يُسْجَنَ أَوْ عَذَابٌ أَلِيمٌ

   And they both hastened to the door, and she rent his shirt from behind and they met her husband at the door. She said: What is the punishment of him who intends evil to your wife except imprisonment or a painful chastisement?
   

2. 12:32 قَالَتْ فَذَٰلِكُنَّ ٱلَّذِى لُمْتُنَّنِى فِيهِ وَلَقَدْ رَٰوَدتُّهُۥ عَن نَّفْسِهِۦ فَٱسْتَعْصَمَ وَلَئِن لَّمْ يَفْعَلْ مَآ ءَامُرُهُۥ لَيُسْجَنَنَّ وَلَيَكُونًا مِّنَ ٱلصَّٰغِرِينَ

   She said: This is he with respect to whom you blamed me, and certainly I sought his yielding himself (to me), but he abstained, and if he does not do what I bid him, he shall certainly be imprisoned, and he shall certainly be of those who are in a state of ignominy.
   

3. 12:33 قَالَ رَبِّ ٱلسِّجْنُ أَحَبُّ إِلَىَّ مِمَّا يَدْعُونَنِىٓ إِلَيْهِ وَإِلَّا تَصْرِفْ عَنِّى كَيْدَهُنَّ أَصْبُ إِلَيْهِنَّ وَأَكُن مِّنَ ٱلْجَٰهِلِينَ

   He said: My Lord! the prison house is dearer to me than that to which they invite me; and if Thou turn not away their device from me, I will yearn towards them and become (one) of the ignorant.
   

4. 12:35 ثُمَّ بَدَا لَهُم مِّنۢ بَعْدِ مَا رَأَوُا۟ ٱلْءَايَٰتِ لَيَسْجُنُنَّهُۥ حَتَّىٰ حِينٍ

   Then it occurred to them after they had seen the signs that they should imprison him till a time.
   

5. 12:36 وَدَخَلَ مَعَهُ ٱلسِّجْنَ فَتَيَانِ قَالَ أَحَدُهُمَآ إِنِّىٓ أَرَىٰنِىٓ أَعْصِرُ خَمْرًا وَقَالَ ٱلْءَاخَرُ إِنِّىٓ أَرَىٰنِىٓ أَحْمِلُ فَوْقَ رَأْسِى خُبْزًا تَأْكُلُ ٱلطَّيْرُ مِنْهُ نَبِّئْنَا بِتَأْوِيلِهِۦٓ إِنَّا نَرَىٰكَ مِنَ ٱلْمُحْسِنِينَ

   And two youths entered the prison with him. One of them said: I saw myself pressing wine. And the other said: I saw myself carrying bread on my head, of which birds ate. Inform us of its interpretation; surely we see you to be of the doers of good.
   

6. 12:39 يَٰصَىٰحِبَىِ ٱلسِّجْنِ ءَأَرْبَابٌ مُّتَفَرِّقُونَ خَيْرٌ أَمِ ٱللَّهُ ٱلْوَٰحِدُ ٱلْقَهَّارُ

   O my two mates of the prison! are sundry lords better or Allah the One, the Supreme?
   

7. 12:41 يَٰصَىٰحِبَىِ ٱلسِّجْنِ أَمَّآ أَحَدُكُمَا فَيَسْقِى رَبَّهُۥ خَمْرًا وَأَمَّا ٱلْءَاخَرُ فَيُصْلَبُ فَتَأْكُلُ ٱلطَّيْرُ مِن رَّأْسِهِۦ قُضِىَ ٱلْأَمْرُ ٱلَّذِى فِيهِ تَسْتَفْتِيَانِ

   O my two mates of the prison! as for one of you, he shall give his lord to drink wine; and as for the other, he shall be crucified, so that the birds shall eat from his head, the matter is decreed concerning which you inquired.
   

8. 12:42 وَقَالَ لِلَّذِى ظَنَّ أَنَّهُۥ نَاجٍ مِّنْهُمَا ٱذْكُرْنِى عِندَ رَبِّكَ فَأَنسَىٰهُ ٱلشَّيْطَٰنُ ذِكْرَ رَبِّهِۦ فَلَبِثَ فِى ٱلسِّجْنِ بِضْعَ سِنِينَ

   And he said to him whom he knew would be delivered of the two: Remember me with your lord; but the Shaitan caused him to forget mentioning (it) to his lord, so he remained in the prison a few years.
   

9. 12:100 وَرَفَعَ أَبَوَيْهِ عَلَى ٱلْعَرْشِ وَخَرُّوا۟ لَهُۥ سُجَّدًا وَقَالَ يَٰٓأَبَتِ هَٰذَا تَأْوِيلُ رُءْيَٰىَ مِن قَبْلُ قَدْ جَعَلَهَا رَبِّى حَقًّا وَقَدْ أَحْسَنَ بِىٓ إِذْ أَخْرَجَنِى مِنَ ٱلسِّجْنِ وَجَآءَ بِكُم مِّنَ ٱلْبَدْوِ مِنۢ بَعْدِ أَن نَّزَغَ ٱلشَّيْطَٰنُ بَيْنِى وَبَيْنَ إِخْوَتِىٓ إِنَّ رَبِّى لَطِيفٌ لِّمَا يَشَآءُ إِنَّهُۥ هُوَ ٱلْعَلِيمُ ٱلْحَكِيمُ

   And he raised his parents upon the throne and they fell down in prostration before him, and he said: O my father! this is the significance of my vision of old; my Lord has indeed made it to be true; and He was indeed kind to me when He brought me forth from the prison and brought you from the desert after the Shaitan had sown dissensions between me and my brothers, surely my Lord is benignant to whom He pleases; surely He is the Knowing, the Wise.
   

10. 26:29 قَالَ لَئِنِ ٱتَّخَذْتَ إِلَٰهًا غَيْرِى لَأَجْعَلَنَّكَ مِنَ ٱلْمَسْجُونِينَ

    Said he: If you will take a god besides me, I will most certainly make you one of the imprisoned.
    

11. 83:7 كَلَّآ إِنَّ كِتَٰبَ ٱلْفُجَّارِ لَفِى سِجِّينٍ

    Nay! most surely the record of the wicked is in the Sijjin.
    

12. 83:8 وَمَآ أَدْرَىٰكَ مَا سِجِّينٌ

    And what will make you know what the Sijjin is?
