The word(s) "thieves" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) At length when he had furnished them forth with provisions (suitable) for them, he put the drinking cup into his brother's saddle-bag. Then shouted out a crier: "O ye (in) the caravan! behold! ye are thieves, without doubt!"

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