1. 3:37 فَتَقَبَّلَهَا رَبُّهَا بِقَبُولٍ حَسَنٍ وَأَنۢبَتَهَا نَبَاتًا حَسَنًا وَكَفَّلَهَا زَكَرِيَّا كُلَّمَا دَخَلَ عَلَيْهَا زَكَرِيَّا ٱلْمِحْرَابَ وَجَدَ عِندَهَا رِزْقًا قَالَ يَٰمَرْيَمُ أَنَّىٰ لَكِ هَٰذَا قَالَتْ هُوَ مِنْ عِندِ ٱللَّهِ إِنَّ ٱللَّهَ يَرْزُقُ مَن يَشَآءُ بِغَيْرِ حِسَابٍ

   So her Lord accepted her with a good acceptance and made her grow up a good growing, and gave her into the charge of Zakariya; whenever Zakariya entered the sanctuary to (see) her, he found with her food. He said: O Marium! whence comes this to you? She said: It is from Allah. Surely Allah gives to whom He pleases without measure.
   

2. 3:44 ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ وَمَا كُنتَ لَدَيْهِمْ إِذْ يُلْقُونَ أَقْلَٰمَهُمْ أَيُّهُمْ يَكْفُلُ مَرْيَمَ وَمَا كُنتَ لَدَيْهِمْ إِذْ يَخْتَصِمُونَ

   This is of the announcements relating to the unseen which We reveal to you; and you were not with them when they cast their pens (to decide) which of them should have Marium in his charge, and you were not with them when they contended one with another.
   

3. 4:85 مَّن يَشْفَعْ شَفَٰعَةً حَسَنَةً يَكُن لَّهُۥ نَصِيبٌ مِّنْهَا وَمَن يَشْفَعْ شَفَٰعَةً سَيِّئَةً يَكُن لَّهُۥ كِفْلٌ مِّنْهَا وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ مُّقِيتًا

   Whoever joins himself (to another) in a good cause shall have a share of it, and whoever joins himself (to another) in an evil cause shall have the responsibility of it, and Allah controls all things.
   

4. 16:91 وَأَوْفُوا۟ بِعَهْدِ ٱللَّهِ إِذَا عَٰهَدتُّمْ وَلَا تَنقُضُوا۟ ٱلْأَيْمَٰنَ بَعْدَ تَوْكِيدِهَا وَقَدْ جَعَلْتُمُ ٱللَّهَ عَلَيْكُمْ كَفِيلًا إِنَّ ٱللَّهَ يَعْلَمُ مَا تَفْعَلُونَ

5. 20:40 إِذْ تَمْشِىٓ أُخْتُكَ فَتَقُولُ هَلْ أَدُلُّكُمْ عَلَىٰ مَن يَكْفُلُهُۥ فَرَجَعْنَٰكَ إِلَىٰٓ أُمِّكَ كَىْ تَقَرَّ عَيْنُهَا وَلَا تَحْزَنَ وَقَتَلْتَ نَفْسًا فَنَجَّيْنَٰكَ مِنَ ٱلْغَمِّ وَفَتَنَّٰكَ فُتُونًا فَلَبِثْتَ سِنِينَ فِىٓ أَهْلِ مَدْيَنَ ثُمَّ جِئْتَ عَلَىٰ قَدَرٍ يَٰمُوسَىٰ

   When your sister went and said: Shall I direct you to one who will take charge of him? So We brought you back to your mother, that her eye might be cooled and she should not grieve and you killed a man, then We delivered you from the grief, and We tried you with (a severe) trying. Then you stayed for years among the people of Madyan; then you came hither as ordained, O Musa.
   

6. 21:85 وَإِسْمَٰعِيلَ وَإِدْرِيسَ وَذَا ٱلْكِفْلِ كُلٌّ مِّنَ ٱلصَّٰبِرِينَ

   And Ismail and Idris and Zulkifl; all were of the patient ones;

   Surely this is my brother; he has ninety-nine ewes and I have a single ewe; but he said: Make it over to me, and he has prevailed against me in discourse.
   

9. 38:48 وَٱذْكُرْ إِسْمَٰعِيلَ وَٱلْيَسَعَ وَذَا ٱلْكِفْلِ وَكُلٌّ مِّنَ ٱلْأَخْيَارِ
