quran:12:13 –

˹Jacob˺ said, "Indeed, it saddens me that you should take him, and I fear that a wolf would eat him while you are of him unaware."  

He said, ‘Lo! It grieves me that you should go with him, that is, your departure ˹with him grieves me˺, because I would be separated from him, and I fear lest the wolf devour him (al-dhi’b here represents the genus, for their land had many wolves in it), while you are heedless of him’, distracted ˹by something else˺.
القرآن:١٢:١٣ –

قَالَ إِنِّي لَيَحْزُنُنِي أَنْ تَذْهَبُوا بِهِ وَأَخَافُ أَنْ يَأْكُلَهُ الذِّئْبُ وَأَنْتُمْ عَنْهُ غَافِلُونَ  

{قال إني ليحزنني أن تذهبوا} أي ذهابكم {به} لفراقه {وأخاف أن يأكله الذئب} المراد به الجنس وكانت أرضهم كثيرة الذئاب {وأنتم عنه غافلون} مشغلون.
