Translation:

73. (The brothers) said: "By Allah! well ye know that we came not to make mischief in the land and we are no thieves!"

Notes (Tafseer)

1738. As strangers in a strange land, they were liable to be suspected as spies or men who meditated some unlawful design, or some crime, such as theft, which would be common in a season of scarcity. The brothers protested against the absurdity of such a suspicion after they had been entertained so royally by the Wazir.
