Prophet yousaf had comitted 8 thefts
(1- tafseer jalaalain page 193
2- tarjamaanulkoran, volume 5, page 788 )
At one point in time, Joseph was accused of being a thief. The story is in fact relayed in the Qur'an (and the Bible, Genesis 37-50):
"They said: If he stealeth, a brother of his stole before. But Joseph kept it secret in his soul and revealed it not unto them. He said (within himself): Ye are in worse case, and Allah knoweth best (the truth of) that which ye allege." (12:77)
Abdullah Yusuf Ali writes in his Tafseer: "The hatred of the ten for Joseph and Benjamin comes out again. They are not only ready to believe evil of Benjamin, but they carry their thoughts back to Joseph and call him a thief as well. They had injured Joseph; and by a ** false ** charge of this kind they salve their conscience. Little did they suspect that Joseph was before them, under another guise, and their falsehood and treachery would soon be exposed."
This verse supercedes the hadith. As far as the Quran is concerned Joseph did not commit any unlawful thefts. Sunni's take the word of the Qur'an over the word of Hadith. I think most Sunni's would be quite offended if they heard someone tell them that they believe Prophet Joseph was a 'thief'. The Hadith literature contains some awkward narration's, some of which are totally unsupported and in some instances contradictory to the Qur'an - they should be viewed at times with skepticism. Most major scholars (Sunni and Shia) have viewed the Hadith literature with skepticism and were generally careful and cautious in their use of Hadith's in their teachings.
