[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."
The Saheeh International Quran Translation
قَالَ إِنِّى لَيَحْزُنُنِىٓ أَن تَذْهَبُوا۟ بِهِۦ وَأَخَافُ أَن يَأْكُلَهُ ٱلذِّئْبُ وَأَنتُمْ عَنْهُ غَٰفِلُونَ[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."
