Translation:

64. He said: "Shall I trust you with him with any result other than when I trusted you with his brother aforetime? But Allah is the best to take care (of him) and He is the Most Merciful of those who show mercy!"

Notes (Tafseer)

1725. I construe Jacob's answer to be a flat refusal to let Benjamin go with them. It would be like the former occasion when he trusted Joseph with them and they lost him. Did they talk of taking care of him? The only protection that he trusted was that of Allah. He at least showed mercy to old and young alike. Did man show such mercy? Witness his sad old age and his lost little Joseph! Would they bring down "his grey hairs with sorrow to the grave?"
